Product details
Overview
MAX6163AESA+T from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering a stable 3.000V output with ±2mV initial accuracy and 5ppm/°C max temperature coefficient over -40°C to +85°C. It sources up to 5mA, sinks 2mA, operates from (VOUT + 200mV) to 12.6V, and requires no external compensation capacitor-ideal for high-accuracy ADC biasing in portable instrumentation.
For engineers reviewing the MAX6163AESA+T datasheet, MAX6163AESA+T pinout, MAX6163AESA+T application, or MAX6163AESA+T equivalent, key selection criteria include its 3.0V output tolerance, ultra-low 100μA quiescent current, 200mV max dropout at 1mA, 35μVP-P (0.1–10Hz) noise, and SO-8 package compatibility with space-constrained battery-powered designs.
Technical Context
The MAX6163AESA+T employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve 5ppm/°C max TCVOUT and ±2mV initial accuracy. Its BiCMOS process enables stable operation with 1μF capacitive loads while eliminating need for external compensation.
As a three-terminal series-mode reference, it draws supply current virtually independent of input voltage (ΔIIN/ΔVIN ≤ 8μA/V), unlike shunt-mode alternatives. Input voltage range is VOUT + 0.2V to 12.6V, supporting direct integration into 3.3V and 5V systems with minimal headroom.
Key Specifications

FAQ
What is the output voltage tolerance and temperature coefficient of MAX6163AESA+T?
MAX6163AESA+T provides a nominal 3.000V output with ±2mV initial accuracy at +25°C and a maximum temperature coefficient of 5ppm/°C over -40°C to +85°C. These specifications are guaranteed per the datasheet's electrical characteristics table and reflect laser-trimming and curvature-correction design enabling high stability without external calibration.
Does MAX6163AESA+T require an external output capacitor for stability?
No, MAX6163AESA+T is internally compensated and does not require an external output capacitor for frequency stability. It remains stable with capacitive loads up to 1μF. An optional 0.1μF ceramic capacitor may be added at the output to improve transient response in applications with step-load changes, but it is not necessary for basic operation.
What is the minimum input voltage required for MAX6163AESA+T to regulate properly?
The minimum input voltage for MAX6163AESA+T is VOUT + 200mV = 3.2V at 1mA load current. The device supports input voltages up to 12.6V. Below 3.2V, regulation degrades; the dropout voltage increases nonlinearly below this threshold, and output accuracy is no longer guaranteed per datasheet specifications.
Can MAX6163AESA+T sink current, and what is its maximum sink capability?
Yes, MAX6163AESA+T can both source and sink current. It sinks up to 2mA while maintaining output regulation. Sink current flows from ground into the OUT pin, enabling use in active biasing circuits or bidirectional reference configurations. Performance parameters like load regulation (2.5mV/mA max sinking) and short-circuit current (110mA to GND) are specified in the datasheet.
Is MAX6163AESA+T compatible with standard SO-8 footprints, and what is its RoHS status?
Yes, MAX6163AESA+T uses a standard 8-pin SO package (outline 21-0041) with 1.27mm pitch and is RoHS-compliant and lead-free ("+" suffix denotes lead-free/RoHS package). Its land pattern matches industry-standard SO-8 footprints, enabling drop-in replacement in existing layouts designed for compatible SO-8 voltage references.
