General DescriptionThe MAX6161–MAX6168 are precision, low-dropout,micropower voltage references. These three-terminal devices operate with an input voltage range from (V OUT + 200mV) to 12.6V and are available with output volt-age options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V,4.5V, and 5V. They feature a proprietary curvature-cor-rection circuit and laser-trimmed thin-film resistors that result in a very low temperature coefficient of 5ppm/°C (max) and an initial accuracy of ±2mV (max).Specifications apply to the extended temperature range (-40°C to +85°C).The MAX6161–MAX6168 typically draw only 100µA of supply current and can source 5mA (4mA for MAX6161) or sink 2mA of load current. Unlike conven-tional shunt-mode (two-terminal) references that waste supply current and require an external resistor, these devices offer a supply current that is virtually indepen-dent of the supply voltage (8µA/V variation) and do not require an external resistor. Additionally, the internally compensated devices do not require an external com-pensation capacitor. Eliminating the external compen-sation capacitor saves valuable board area in space-critical applications. A low-dropout voltage and a supply-independent, ultra-low supply current make these devices ideal for battery-operated, high-perfor-mance, low-voltage systems.The MAX6161–MAX6168 are available in 8-pin SO packages.________________________ApplicationsAnalog-to-Digital Converters (ADCs)Portable Battery-Powered Systems Notebook Computers PDAs, GPS, DMMs Cellular PhonesPrecision +3V/+5V Systems____________________________Features♦±2mV (max) Initial Accuracy♦5ppm/°C (max) Temperature Coefficient ♦5mA Source Current at 0.9mV/mA ♦2mA Sink Current at 2.5mV/mA ♦Stable with 1µF Capacitive Loads ♦No External Capacitor Required ♦100µA (typ) Quiescent Supply Current ♦200mV (max) Dropout at 1mA Load Current ♦Output Voltage Options: 1.25V, 1.8V, 2.048V, 2.5V,3V, 4.096V, 4.5V, 5V19-1650; Rev 3; 8/05MAX6161–MAX6168Precision, Micropower, Low-Dropout, High-Output-Current, SO-8 Voltage References________________________________________________________________Maxim Integrated Products 1___________________Pin Configuration*Insert the code for the desired initial accuracy and temperature coefficient (from the Selector Guide) in the blank to complete the part number.Typical Operating Circuit and Selector Guide appear at end of data sheet.Ordering InformationFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 6161–M A X 6168Precision, Micropower, Low-Dropout, High-Output-Current, SO-8 Voltage References 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The extremes of these characteristicsare found in the MAX6161 (1.25V output) and the MAX6165 (5.0V output). The Typical Operating Characteristics of the remain-der of the MAX6161 family typically lie between these two extremes and can be estimated based on their output voltages.Typical Operating Characteristics (continued)(V IN = +5V for MAX6161–MAX6168, V IN = +5.5V for MAX6165, I OUT = 0, T A = +25°C, unless otherwise noted.)

Locate the capacitor as close to IN as possible. When transient performance is less important, no capacitor is necessary.Output/Load CapacitanceDevices in the MAX6161 family do not require an output capacitor for frequency stability. In applications where the load or the supply can experience step changes,an output capacitor of at least 0.1µF will reduce the amount of overshoot (undershoot) and improve the cir-cuit’s transient response. Many applications do not require an external capacitor, and the MAX6161 family can offer a significant advantage in applications when board space is critical.Supply CurrentThe quiescent supply current of the series-mode MAX6161 family is typically 100µA and is virtually inde-pendent of the supply voltage, with only an 8µA/V (max) variation with supply voltage. Unlike series refer-ences, shunt-mode references operate with a series resistor connected to the power supply. The quiescent current of a shunt-mode reference is thus a function of the input voltage. Additionally, shunt-mode references have to be biased at the maximum expected load cur-rent, even if the load current is not present at the time.In the MAX6161 family, the load current is drawn from the input voltage only when required, so supply current is not wasted and efficiency is maximized at all input voltages. This improved efficiency reduces power dissi-pation and extends battery life.When the supply voltage is below the minimum speci-fied input voltage (as during turn-on), the devices can draw up to 400µA beyond the nominal supply current.The input voltage source must be capable of providing this current to ensure reliable turn-on.Output Voltage HysteresisOutput voltage hysteresis is the change in the input voltage at T A = +25°C before and after the device is cycled over its entire operating temperature range.Hysteresis is caused by differential package stress appearing across the bandgap core transistors. The typical temperature hysteresis value is 125ppm.Turn-On TimeThese devices typically turn on and settle to within 0.1% of their final value in 50µs to 300µs, depending on the output voltage (see electrical table of part used).The turn-on time can increase up to 1.5ms with the device operating at the minimum dropout voltage and the maximum load.Typical Operating Circuit__________________________Chip Information TRANSISTOR COUNT: 117PROCESS: BiCMOSPin DescriptionPIN NAME FUNCTIONNo Connection.
