With a wide supply voltage range from 5 V to 24 V, and the ability to operate on single supplies, with a bandwidth of 145 MHz, the AD8065-KGD-CHIP is designed to work in a variety of applications. For added versatility, the amplifier also features a rail-to-rail output.Despite the low cost, the amplifiers provide excellent overall performance. The differential gain and phase errors of 0.02% and 0.02°, respectively, along with 0.1 dB flatness out to 7 MHz, make these amplifiers ideal for video applications. Additionally, they offer a high slew rate of 180 V/µs, excellent distortion (SFDR of −88 dBc at 1 MHz), extremely high common-mode rejection of −100 dB, and a low input offset voltage of 1.5 mV maximum under warmed up conditions. The AD8065-KGD-CHIP operates using only a 6.4 mA/amplifier typical supply current and are capable of delivering up to 30 mA of load current.The AD8065-KGD-CHIP is rated to work over the industrial temperature range of −40°C to +85°C.Additional application and technical information can be found in the AD8065 data sheet.1Protected by U.S. patent numbers 6,486,737B1; 6,518,842B11112 Specifications (3)Absolute Maximum Ratings (5)5677 Ordering Guide (7)REVISION HISTORY10/12—Revision 0: Initial VersionRev. 0 | Page 2 of 8−3 dB Bandwidth G = +1, V O = 0.2 V p-p100 145 GBD1MHzG = +2, V O = 0.2 V p-p 50 MHzG = +2, V O = 2 V p-p 42 MHz Bandwidth for 0.1 dB Flatness G = +2, V O = 0.2 V p-p 7 MHz Input Overdrive Recovery Time G = +1, −5.5 V to +5.5 V 175 ns Output Recovery Time G = −1, −5.5 V to +5.5 V 170 ns Slew Rate G = +2, V O = 4 V step 130 180 GBD1V/µs Settling Time to 0.1% G = +2, V O = 2 V step 55 nsG = +2, V O = 8 V step 205 ns NOISE/HARMONIC PERFORMANCESFDR f C = 1 MHz, G = +2, V O = 2 V p-p −88 dBcf C = 5 MHz, G = +2, V O = 2 V p-p −67 dBcf C = 1 MHz, G = +2, V O = 8 V p-p −73 dBc Third-Order Intercept f C = 10 MHz, R L = 100 Ω 24 dBm Input Voltage Noise f = 10 kHz 7 nV/√Hz Input Current Noise f = 10 kHz 0.6 fA/√Hz Differential Gain Error NTSC, G = +2, R L = 150 Ω 0.02 % Differential Phase Error NTSC, G = +2, R L = 150 Ω 0.02 Degrees DC PERFORMANCEInput Offset Voltage V CM = 0 V 0.4 1.5 Tested mV Input Offset Voltage Drift 1 17 GBD1µV/°C Input Bias Current 2 pAT MIN to T MAX25 pA Input Offset Current 1 pAT MIN to T MAX 1 pA Open-Loop Gain V O = ±3 V, R L = 1 kΩ 100 113 Tested dB INPUT CHARACTERISTICSCommon-Mode Input Impedance 1000 || 2.1 GΩ || pF Differential Input Impedance 1000 || 4.5 GΩ || pF Input Common-Mode Voltage RangeFET Input Range −5 to +1.7 −5.0 to +2.4 GBD1V Common-Mode Rejection Ratio V CM = −1 V to +1 V −85 −100 Tested dB OUTPUT CHARACTERISTICS−4.94 to +4.95 Tested V Output Voltage Swing R L = 1 kΩ −4.88 to+4.9R L = 150 Ω −4.8 to +4.7 V Output Current V O = 9 V p-p, SFDR ≥ −60 dBc,35 mAf = 500 kHzShort-Circuit Current 90 mA Capacitive Load Drive 30% overshoot G = +1 20 pF POWER SUPPLYOperating Range 5 24 Tested V Quiescent Current per Amplifier 6.4 7.2 Tested mA Power Supply Rejection Ratio V S ± 2 V −85 −100 Tested dB1 GBD = Guaranteed By Design.Rev. 0 | Page 3 of 8100 145 1Slew Rate G = +2, V O = 4 V step 130 180 GBD1V/µs DC PERFORMANCEInput Offset Voltage V CM = 0 V 0.4 1.5 Tested mV Input Offset Voltage Drift 1 17 GBD1µV/°C Input Bias Current 3 pA Input Offset Current 2 pA Open-Loop Gain V O = ±10 V 103 114 Tested dB INPUT CHARACTERISTICSInput Common-Mode Voltage RangeFET Input Range −12 to +8.5 −12.0 to +9.5 GBD1V Common-Mode Rejection Ratio V CM = −1 V to +1 V −85 −100 Tested dB OUTPUT CHARACTERISTICSOutput Voltage Swing R L = 1 kΩ −11.8 to +11.8 −11.9 to +11.9 Tested V POWER SUPPLYPower Supply Rejection Ratio V S ± 2 V −84 −93 Tested dB Quiescent Current per Amplifier 6.6 7.4 Tested mA 1 GBD = Guaranteed By Design.V S = +5 V at T A = 30°C, R L = 1 kΩ to midsupply, unless otherwise noted.Table 3.Parameter Test Conditions/Comments Min Typ Max Status Unit DYNAMIC PERFORMANCE−3 dB Bandwidth G = +1, V O = 0.2 V p-p125 155 GBD1MHz Slew Rate G = +2, V O = 2 V step 105 160 GBD1V/µs DC PERFORMANCEInput Offset Voltage V CM = 1.0 V 0.4 1.5 Tested mV Input Offset Voltage Drift 1 17 GBD1µV/°C Input Bias Current 1 pA Input Offset Current 1 pA Open-Loop Gain V O = 1 V to 4 V 100 113 Tested dB INPUT CHARACTERISTICSInput Common-Mode Voltage RangeFET Input Range 0 to 1.7 0 to 2.4 GBD1V Common-Mode Rejection Ratio V CM = 1 V to 2 V −78 −91 Tested dB OUTPUT CHARACTERISTICSOutput Voltage Swing R L = 1 kΩ 0.1 to 4.85 0.03 to 4.95 Tested V POWER SUPPLYPower Supply Rejection Ratio V S ± 2 V −78 −100 Tested dB Quiescent Current per Amplifier 6.4 7.0 Tested mA 1 GBD = Guaranteed by Design.Rev. 0 | Page 4 of 8Differential Input Voltage ±1.8 VStorage Temperature –65°C to +125°COperating Temperature Range –40°C to +105°CJunction Temperature 150°CStresses above those listed under Absolute Maximum Ratingsmay cause permanent damage to the device.

轨到轨运放常用型号

轨到轨运放常用型号
轨到轨运放是一种特殊的运算放大器，其输入和输出电压可以接近或达到供电电源的极限值。

这种运放的特点是具有轨到轨的输入和输出摆幅，因此得名。

轨到轨运放常用型号有：μA741、μA747、AD515A、AD605、AD644、AD648、AD704、AD705、AD706、AD707、AD708、AD711、AD712、AD713、AD741、AD743、AD744、AD745、AD746、AD748、MS8551/8552/8554等。

轨到轨运放的应用非常广泛，特别是在需要高精度、高速、低噪声的信号处理电路中。

由于其输入和输出电压范围大，可以有效地减小电路中的失真和噪声，提高信号的动态范围和信噪比。

此外，轨到轨运放的带宽增益乘积为常数，因此其带宽与增益之间不存在冲突，使得它在许多应用中成为理想的选择。

需要注意的是，轨到轨运放也有一些局限性。

例如，由于其输出摆幅较大，可能会导致放大器在某些情况下容易受到电源噪声的干扰。

此外，轨到轨运放的增益和带宽等性能参数也会受到限制，因此需要根据实际应用需求进行选择和优化。

器件支持单端，差分模拟输入信号，范围可以是±4VREF或者±2VREF ，最大输入电压可以达到±12V。

器件提供了一个内部的2.5V/3V参考电压源，配合一个10-bit的DA转换器，可以提供2.44mV或2.93mV的步进调整电压。

ADS8556/7/8同样提供一个可选择的并行或串行接口，可以用在硬件模式或软件模式中模拟部分本节讲述模拟输入电路，ADC以及控制信号，以及器件的参考设计模拟输入输入和转换器可以是单端或差分类型，绝对电压范围可以通过使用RANGE引脚进行配置（硬件模式）或控制寄存器（CR）中的RANGE_x位设置为±4V REF或±2V REF。

当使用的参考电压为2.5V时(CR bit C18 = 0),输入电压范围可以是±10V或±5V；当使用的参考电压为3V (CR bit C18 = 1),输入电压范围可以是±12V或±6V。

RANGE引脚在BUSY(如果CR bit C20 = 0)的下降沿锁存。

模拟输入端的输入电流取决于采样率，输入电压和信号的源阻抗。

实质上，模拟输入端的电流仅在采样周期(t ACQ)为内部的电容阵列进行充电。

在最大速率下（280ns），模拟输入电压的源必须能够为10pF的输入电容（±4V REF）或20pF（±2V REF）的输入电容充电。

The RF section of the transmitter comprises a fre-quency synthesiser which provides 100mW of frequency modulated RF drive to a two stage, wide band output driver followed by a 25W power amplifier. A thermal shut-down feature is provided in the T856 in case operating temperatures exceed acceptable levels.The T857 is a synthesised, microprocessor controlled FM base station exciter designed for single or multichannel operation in the 400 to 520MHz frequency range1. With a standard power output of only 1W, the exciter is designed for use with the T858 50W or T859 100W power amplifiers. The RF section of the exciter comprises a frequency syn-thesiser which provides 100mW of frequency modulated RF drive to a two stage, wide band output amplifier.A wide selection of audio characteristics may be obtained from the audio processor. Optional circuit blocks are an audio compressor and a pre-emphasis stage. They can be bypassed or linked to one or both audio inputs, and then back into the remaining audio circuitry in almost any combination. All audio processor options are link selectable. The synthesiser frequency is programmed via the serial communications port. Eight channel select lines are accessible via an optional D-range connector (D-range 2 -T800-03-0000) at the rear of the set.All components except those of the VCO are mounted on a single PCB. This is secured to a die-cast chassis which is divided into compartments to individually shield each sec-tion of circuitry. Access to both sides of the main circuit board is obtained by removing each of the chassis lids. There is provision within the chassis to mount small option PCBs.The front panel controls include line sensitivity, microphone socket and carrier switch. This switch turns on the carrier (unmodulated) as an aid to servicing.The T856 and T857 are both 60mm wide and each occupies a single space in a Tait rack frame, which has the ability to accommodate up to seven standard modules.1.Although capable of operating over the 400-520MHz frequency range, the T856 andT857 have an 8MHz switching range (see Section 1.2.3 and Section 3.1).1.2Specifications1.2.1IntroductionThe performance figures given are minimum figures, unless otherwise indicated, for equipment tuned with the maximum switching range and operating at standard room temperature (+22°C to +28°C) and standard test voltage (13.8V DC).Where applicable, the test methods used to obtain the following performance figures are those described in the EIA and ETS specifications.

运放轨对轨技术详解

随着单电源运放的广泛的运用，运放的轨至轨输入（rail to rail input）成为一个时髦的词。

现在大部分低电压单电源供电的运放都是轨至轨输入的。

TI 在轨至轨输入的运放产品方面具有十分领先的优势。

本文介绍运放的 rail to rail 输入的实现以及 TI 在实现运放的 rail to rail 输入方面的领先技术。

先说两句废话，解释一下轨至轨，这里的轨指的是电源轨，运放的两个电源供电电压如+/-15V。

这两个电源电压就像两条平行的距离为 30V 的“轨道”一样限制了运放的输入输出信号。

运放的轨至轨输入是指运放的输入端信号电压能够达到电源的两个轨，并保持不失真，如上例输入信号电压可达到+/-15V。

运放的输入电压范围可在运放的 datasheet 中找到。

就是共模电压范围 Vcm（Common-Mode Voltage Range）。

如下表即为 OPA365 的输入电压范围，可见它是典型的轨至轨输入运放。

一般的 BJT 和 JFET 是非轨至轨输入的运放。

如下表所示为 OPA827 共模输入电压范围为(V-)+3V 至(V+)-3V，典型的非轨至轨运放。

单电源（我们暂且称之为“单电源”）运放的输入级通常有三种结构，第一种是采用 PMOS 做差分输入级。

这样的运入输入级电压可以低于负电源轨 0.2 甚至 0.3V，但达不到正电源轨，如 OPA336。

下表是 datasheet 中标出的 OPA336 输入电压范围。

它的输入级原理框图如下图，典型的 PMOS 差分输入级。

既然 PMOS 差分输入级输入电压不能达到正电源轨， NMOS 那呢，对头，NMOS 差分输入级的输入电压可以达到正电源轨，但是达不到负电源轨，一般会在负电源轨的 1.2V 之上。

此时有人想到了，把 PMOS 和 NMOS 差分输入级并联起来。

在接近电源负电压轨时使 PMOS 差分输入级工作，在接近电源正电源轨时使 NMOS 差分输入级工作。

GENERAL DESCRIPTION The AD8565, AD8566, and AD8567 are low cost, single-supply rail-to-rail input and output operational amplifiers optimized for LCD monitor applications. They are built on an advanced high voltage CBCMOS process. The AD8565 contains a single amplifier, the AD8566 has two amplifiers, and the AD8567 has four amplifiers. These LCD op amps have high slew rates, 35 mA continuous output drive, 250 mA peak output drive, and high capacitive load drive capability. They have a wide supply range and offset voltages below 10 mV. The AD8565, AD8566, and AD8567 are ideal for LCD grayscale reference buffer and VCOM applications. The AD8565, AD8566, and AD8567 are specified over the –40°C to +85°C temperature range. The AD8565 single is available in a 5-lead SC70 package. The AD8566 dual is available in an 8-lead MSOP package. The AD8567 quad is available in 14-lead TSSOP and 16-lead LFCSP packages.
