They have a single-supply operating voltage of 1.8V to 5V. The com-mon-mode input range extends from -0.1V below the negative supply to within 0.7V of the positive supply.They require approximately 60µA per comparator with a 5V supply and 40µA with a 2.7V supply.The LMX331H/LMX393H/LMX339H have 2mV of hys-teresis for noise immunity. This significantly reduces the chance of output oscillations even with slow-moving input signals. The LMX331/LMX393/LMX339 and LMX331H/LMX393H/LMX339H are ideal for automotive applications because they operate from -40°C to +125°C (see Typical Operating Characteristics ).Applications InformationHysteresisMany comparators oscillate in the linear region of oper-ation because of noise or undesired parasitic feed-back. This tends to occur when the voltage on one input is equal or very close to the voltage on the other input. The LMX331H/LMX393H/LMX339H have internal hysteresis to counter parasitic effects and noise.The hysteresis in a comparator creates two trip points:one for the rising input voltage and one for the fallinginput voltage (Figure 1). The difference between the trip points is the hysteresis. When the comparator's input voltages are equal, the hysteresis effectively causes one comparator input to move quickly past the other,thus taking the input out of the region where oscillation occurs. This provides clean output transitions for noisy,slow-moving input signals.Additional hysteresis can be generated with two resis-tors, using positive feedback (Figure 2). Use the follow-ing procedure to calculate resistor values:Figure 1.

In this example, we will choose 1k Ω.Select V HYST . In this example, we will choose 50mV.Solve for R1:V HYST = V OUT(HIGH)(R2 / (R1 + R2)) V0.050V = 5(1000 / (R1 + 1000)) Vwhere R1 ≈100k Ω, V TH = 2.525V, and V TL = 2.475V.Choose R1 and R2 to be large enough as not to exceed the amount of current the reference can supply.The source current required is V REF / (R1 + R2).The sink current is (V OUT(HIGH)- V REF ) ✕(R1 + R2).Choose R L to be large enough to avoid drawing excess current, yet small enough to supply the necessary cur-rent to drive the load. R L should be between 1k Ωand 10k Ω.Board Layout and BypassingUse 0.1µF bypass capacitors from V DD to V SS . To max-imize performance, minimize stray inductance by putting this capacitor close to the V DD pin and reduc-ing trace lengths. For slow-moving input signals (rise time > 1ms), use a 1nF capacitor between IN+ and IN-to reduce high-frequency noise.Chip InformationLMX331/LMX331H TRANSISTOR COUNT: 112LMX393/LMX393H TRANSISTOR COUNT: 211LMX339/LMX339H TRANSISTOR COUNT: 411Figure 2.

LM339/LM393中文资料及PDF下载什么是lm339LM339/LM393是四电压比较器集成电路。
由于LM339 使用灵活，应用广泛，所以世界上各大IC 生产厂、公司竟相推出自己的四比较器，如IR2339、ANI339、SF339 等，它们的参数基本一致，可互换使用。
LM339 类似于增益不可调的运算放大器。
每个比较器有两个输入端和一个输出端。
两个输入端一个称为同相输入端，用“+”表示，另一个称为反相输入端，用“-”表示。
用作比较两个电压时，任意一个输入端加一个固定电压做参考电压（也称为门限电平，它可选择LM339 输入共模范围的任何一点），另一端加一个待比较的信号电压。
当“+”端电压高于“-”端时，输出管截止，相当于输出端开路。
当“-”端电压高于“+”端时，输出管饱和，相当于输出端接低电位。
两个输入端电压差别大于10mV 就能确保输出能从一种状态可靠地转换到另一种状态，因此，把LM339 用在弱信号检测等场合是比较理想的。
LM339 的输出端相当于一只不接集电极电阻的晶体三极管，在使用时输出端到正电源一般须接一只电阻（称为上拉电阻，选3-15K）。
选不同阻值的上拉电阻会影响输出端高电位的值。
因为当输出晶体三极管截止时，它的集电极电压基本上取决于上拉电阻与负载的值。
另外，各比较器的输出端允许连接在一起使用。
�8�5 图1a 给出了一个基本单限比较器。
输入信号Uin，即待比较电压，它加到同相输入端，在反相输入端接一个参考电压（门限电平）Ur。
当输入电压Uin>Ur 时，输出为高电平U OH 。
