Product details
Overview
MAX6176BASA+ from Maxim Integrated is a high-precision, low-noise 10V voltage reference with integrated temperature sensor output, featuring ±0.1% initial accuracy, 3ppm/°C max temperature coefficient over –40°C to +125°C, and 18µVP-P (0.1Hz–10Hz) noise - used in 16-bit ADC/DAC systems requiring stable reference and on-die thermal monitoring.
For engineers reviewing the MAX6176BASA+ datasheet, MAX6176BASA+ pinout, MAX176BASA+ application, or MAX6176BASA+ equivalent, key selection criteria include guaranteed 10V output stability under 12V–40V input, TRIM-adjustable output range (±3% to ±6%), TEMP output linearity (2.1mV/°C), and AEC-Q100-compatibility for automotive-grade designs.
Technical Context
The MAX6176BASA+ employs bandgap-based architecture with proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve ultra-low drift and tight initial tolerance. Its internal TEMP output is directly proportional to junction temperature (TJ), calibrated at 2.1mV/°C, enabling accurate die-temperature sensing without external components.
It integrates short-circuit protection (60mA sink to GND, 3mA sink to IN), operates without mandatory output bypass capacitors, and maintains stability with capacitive loads up to 100µF - eliminating board-area overhead while supporting fast load transients in precision data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.0V nominal, ±0.1% initial accuracy (9.990V–10.010V at +25°C) - ensures ≤1 LSB error in 16-bit converters across full temp range. |
| Tempco (TCVOUT) | 3ppm/°C max (–40°C to +125°C) - enables <±0.003% output drift over automotive temperature range. |
| Noise (0.1Hz–10Hz) | 18µVP-P - supports high-resolution metrology applications where sub-µV noise impacts effective resolution. |
| Supply Current | 340µA typ / 550µA max at +25°C - minimizes self-heating and extends battery life in portable instrumentation. |
| TEMP Output | 630mV at +25°C, 2.1mV/°C slope - provides direct, factory-calibrated die temperature measurement with ±1.5°C typical accuracy. |
| Input Voltage Range | +12.0V to +40.0V - accommodates wide-input industrial and automotive supplies with ≥2V headroom margin. |
| Load Drive | Sources up to 30mA / sinks up to 2mA - drives ADC reference inputs, op-amp buffers, and small analog subsystems directly. |
Pinout & Package
MAX6176BASA+ is housed in an 8-pin SO (Small Outline) package (package code S8+4, outline 21-0041), RoHS-compliant, with exposed pad not electrically connected. Pin 1 and Pin 8 are internally connected (I.C.) and must remain unconnected externally; Pin 7 is no-connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2: IN | Positive power-supply input | Accepts 12V–40V supply; requires local 0.1µF ceramic decoupling for optimal line-transient rejection. |
| Pin 3: TEMP | Digital-temperature-sensor analog output | Provides 2.1mV/°C linear voltage proportional to die temperature; high-impedance output - buffer recommended for long traces. |
| Pin 4: GND | Analog ground reference | Must be tied to clean system ground plane; shared return for IN, OUT, TRIM, and TEMP to minimize ground bounce. |
| Pin 5: TRIM | Voltage-reference trim control | Accepts 0V–10V divider tap; adjusts output ±3% (typ) or ±6% (max); open-circuit = factory preset 10.0V. |
| Pin 6: OUT | Precision 10V reference output | Low-impedance buffered output; stable with 0–100µF capacitive loads; short-circuit protected to GND or IN. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5010IDR | 10V, 3ppm/°C max, 0.05% initial accuracy, 12µVP-P noise; requires 1µF output cap for stability; no TEMP output. | Lacks integrated temperature sensor; better noise performance but adds external sensing complexity. | Choose REF5010IDR when lowest possible noise dominates design priority and thermal monitoring is handled separately. |
| ADR4510BRZ | 10V, 3ppm/°C max, 0.02% initial accuracy, 12µVP-P noise; SOIC-8; no TEMP output; higher quiescent current (950µA). | Higher accuracy and lower noise, but no die-temperature sensing and double the supply current. | Choose ADR4510BRZ for metrology-grade calibration equipment where absolute accuracy outweighs power and integration needs. |
Compared with REF5010IDR and ADR4510BRZ, MAX6176BASA+ uniquely combines 10V reference stability, integrated temperature sensing, and ultra-low quiescent current in one SOIC-8 package - making it optimal for space- and power-constrained systems requiring dual-function analog monitoring.

FAQ
What is the guaranteed initial accuracy of the MAX6176BASA+?
The MAX6176BASA+ guarantees ±0.1% initial accuracy at +25°C, corresponding to a 10.0V output tolerance of 9.990V to 10.010V. This specification is tested and binned during production, and applies across the full –40°C to +125°C operating temperature range per the datasheet's MAX6176BASA grade definition.
Does the MAX6176BASA+ require an output bypass capacitor for stability?
No, the MAX6176BASA+ does not require an output bypass capacitor for stability. It is designed to remain stable with capacitive loads from 0 to 100µF. Adding an output capacitor (e.g., 1µF) improves transient response during large load steps but is optional - unlike many references that mandate minimum output capacitance.
How is the TEMP output of the MAX6176BASA+ calibrated and what is its practical accuracy?
The TEMP output of the MAX6176BASA+ is factory-calibrated to 2.1mV/°C with a nominal 630mV output at +25°C. Over –40°C to +125°C, it delivers 300mV to 1130mV. Typical die-temperature accuracy is ±1.5°C when self-heating is minimized - verified by correlation to external thermal sensors under controlled load conditions.
Can the MAX6176BASA+ be used in AEC-Q100 automotive applications?
Yes - the MAX6176BASA+ is explicitly AEC-Q100 qualified (Grade 0: –40°C to +125°C). Its qualification includes stress testing for temperature cycling, humidity, ESD, and lifetime reliability. The "/V" suffix denotes AEC-Q100 versions; MAX6176BASA+ carries this qualification and is approved for use in automotive powertrain, body control, and ADAS modules.
What is the maximum allowable input voltage for the MAX6176BASA+ and how does line regulation behave?
The MAX6176BASA+ accepts input voltages from +12.0V to +40.0V. Line regulation is specified at 0.6–5 ppm/V (typ/max) over this range at +25°C, and 0.8–10 ppm/V across –40°C to +125°C - meaning output variation remains below ±50µV per volt of input change, even at temperature extremes.
