Product details
Overview
MAX6176AASA+T from Maxim Integrated is a high-precision, low-noise voltage reference IC delivering a factory-trimmed +10.0V output with ±0.05% initial accuracy, 1.5–3 ppm/°C temperature coefficient over –40°C to +125°C, and 18 µVP-P (0.1–10 Hz) noise. It integrates a linear temperature transducer (TEMP pin, 2.1 mV/°C) and supports fine output adjustment via TRIM pin. Used in 16-bit ADC/DAC systems requiring stable, low-drift references.
For engineers reviewing the MAX6176AASA+T datasheet, MAX6176AASA+T pinout, MAX6176AASA+T application, or MAX6176AASA+T equivalent, key selection criteria include guaranteed 10V output accuracy at automotive temperature extremes, no-output-capacitor stability up to 100µF, sourcing capability of 30mA, and integrated die-temperature sensing for system-level thermal monitoring.
Technical Context
The MAX6176AASA+T employs bandgap-based architecture with proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve ultra-low temperature drift. Its TEMP output provides a direct analog voltage proportional to junction temperature (2.1 mV/°C), calibrated at 630 mV at +25°C.
It features a dedicated TRIM input enabling ±6% output adjustment using an external resistive divider, and operates with input voltages from 12.0V to 40.0V - supporting wide-supply industrial and automotive rails without external regulation.

FAQ
What is the guaranteed initial accuracy of the MAX6176AASA+T?
The MAX6176AASA+T guarantees ±0.05% initial accuracy at +25°C, corresponding to a ±5 mV tolerance on its +10.0V nominal output. This specification is tested and binned during production, and applies across the full –40°C to +125°C operating range per the device's temperature coefficient specification.
Does the MAX6176AASA+T require an output bypass capacitor for stability?
No, the MAX6176AASA+T does not require an output bypass capacitor for stability. It is internally compensated and remains stable with capacitive loads from 0 to 100 µF. This eliminates board area and cost associated with output capacitance while simplifying layout - especially valuable in space-constrained industrial and automotive modules.
How is the TEMP output of the MAX6176AASA+T used for temperature measurement?
The TEMP pin of the MAX6176AASA+T delivers a voltage proportional to die temperature: 630 mV at +25°C with a slope of 2.1 mV/°C. To measure temperature, read TEMP with a high-impedance ADC and compute TJ = (VTEMP − 630 mV) / 2.1 mV/°C + 25°C. Self-heating effects are minimal below 10 mA load, preserving accuracy.
Can the output voltage of the MAX6176AASA+T be adjusted, and how?
Yes, the MAX6176AASA+T output can be trimmed ±6% using the TRIM pin. Connect a resistive divider (e.g., 50 kΩ potentiometer) between OUT and GND, with the wiper tied to TRIM. The output changes linearly with TRIM voltage: ∆VOUT = 2 × (VTRIM − VOUT/2) × 0.06. No external op-amp is needed.
What is the maximum input voltage the MAX6176AASA+T can tolerate?
The MAX6176AASA+T accepts a supply voltage from 12.0 V to 40.0 V DC on the IN pin. Absolute maximum rating is +42 V, but operation above 40 V is not guaranteed. The wide input range enables direct connection to unregulated 24 V or 36 V industrial and automotive rails without pre-regulation.
