Product details
Overview
MAX6176BASA+T from Maxim Integrated is a high-precision, low-noise voltage reference IC with integrated temperature sensor output. It delivers a factory-trimmed +10.0V output with ±0.1% initial accuracy, 3ppm/°C max temperature coefficient over –40°C to +125°C, and 18µVP-P (0.1Hz–10Hz) noise - enabling use in 16-bit+ data acquisition systems, automotive sensor signal conditioning, and precision power supply monitoring.
For engineers reviewing the MAX6176BASA+T datasheet, MAX6176BASA+T pinout, MAX6176BASA+T application, or MAX6176BASA+T equivalent, key selection criteria include its 10V output stability under wide input range (12V–40V), TRIM-adjustable output (±6%), TEMP output linearity (2.1mV/°C), and AEC-Q100-compatibility for automotive-grade reliability.
Technical Context
The MAX6176BASA+T employs bandgap-based architecture with proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve ultra-low drift. Its internal TEMP output is directly proportional to die temperature (2.1mV/°C), calibrated at +25°C (630mV), and usable across the full –40°C to +125°C range without external compensation.
It features active short-circuit protection (60mA sink to GND, 3mA sink to IN), operates without mandatory output bypass capacitors, and remains stable with capacitive loads up to 100µF - simplifying layout in space-constrained industrial and automotive modules.
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 ADCs over full temp range |
| Tempco (TCVOUT) | 3ppm/°C max (–40°C to +125°C) - enables <±0.01% output drift over automotive temperature range |
| Noise (0.1Hz–10Hz) | 18µVP-P - supports high-resolution measurement without added filtering overhead |
| Supply Current | 340µA typical, 550µA max at +25°C - extends battery life in portable instrumentation |
| Input Voltage Range | +12.0V to +40.0V - accommodates unregulated 12V/24V automotive rails with margin |
| TEMP Output | 630mV at +25°C, 2.1mV/°C slope - provides direct die-temperature readout for thermal management |
| Load Drive | Sources up to 30mA, sinks up to 2mA - drives ADC reference inputs and small buffers without external op-amps |
Pinout & Package
The MAX6176BASA+T is housed in an 8-pin SO (Small Outline) package (package code S8+4, outline 21-0041), RoHS-compliant, with standard JEDEC footprint (land pattern 90-0096). Thermal resistance θJA = 132°C/W on multilayer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | I.C. | Internally connected; must remain unconnected externally - no routing or vias allowed |
| 2 | IN | Positive supply input; accepts 12V–40V - requires local 0.1µF ceramic decoupling at pin |
| 3 | TEMP | Temperature-proportional analog output; 630mV @ +25°C, 2.1mV/°C - connect to ADC input with ≥10kΩ series resistor for noise immunity |
| 4 | GND | Analog ground reference; star-point connection required for precision performance |
| 5 | TRIM | Voltage divider tap for ±6% output adjustment - connect between OUT and GND via potentiometer (e.g., MAX5436) |
| 6 | OUT | Stable +10.0V reference output; capable of sourcing 30mA - place output capacitor ≤100µF if needed for transient suppression |
| 7 | N.C. | No internal connection - leave floating; no trace or pad required |
Key Features
| Feature | Design Value |
|---|---|
| Curvature-corrected bandgap core | Reduces temperature-induced nonlinearity, achieving 3ppm/°C max drift without external compensation |
| Integrated linear temperature sensor | Eliminates need for discrete thermistor or digital sensor in thermal monitoring circuits |
| Trim-adjustable output (±6%) | Enables fine calibration of system-level gain/offset without modifying PCB layout |
| No mandatory output capacitor | Saves board area and BOM cost in space-constrained modules (e.g., engine control units) |
| AEC-Q100 qualified (/V variants) | Validated for automotive applications including under-hood temperature sensing and ADAS power rails |

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 output, 3ppm/°C max tempco, but higher 3.8µVP-P noise (0.1Hz–10Hz); requires 1µF output capacitor for stability | Lacks integrated TEMP output; suited for pure reference applications without thermal telemetry | Select when lowest noise is critical and TEMP functionality is unnecessary |
| ADR4510BRZ | 10V output, 3ppm/°C max tempco, 12µVP-P noise; includes enable pin and better PSRR, but no TEMP output or TRIM input | Designed for low-power portable instruments; lacks automotive temp range (–40°C to +125°C) | Select for battery-powered equipment needing ultra-low quiescent current (950µA max) |
Compared with REF5010IDR and ADR4510BRZ, the MAX6176BASA+T uniquely integrates a calibrated temperature sensor and trim capability in an automotive-grade package - making it the only choice when simultaneous high-accuracy referencing and die-temperature monitoring are required in a single 8-pin SO device.

FAQ
What is the guaranteed initial accuracy of the MAX6176BASA+T?
The MAX6176BASA+T guarantees ±0.1% initial output voltage accuracy at +25°C, corresponding to a 10.0V nominal output ranging from 9.990V to 10.010V. This specification is production-tested and applies across the full –40°C to +125°C operating temperature range per the datasheet's electrical characteristics table for MAX6176BASA+T.
Does the MAX6176BASA+T require an output capacitor for stability?
No, the MAX6176BASA+T does not require an output capacitor for stability and is explicitly characterized as stable with capacitive loads up to 100µF. This eliminates the need for a mandatory output bypass capacitor, reducing board area and BOM count - a key advantage in compact automotive and industrial modules where the MAX6176BASA+T is commonly deployed.
How is the TEMP output of the MAX6176BASA+T calibrated and what is its sensitivity?
The TEMP output of the MAX6176BASA+T is calibrated to 630mV at +25°C with a sensitivity of 2.1mV/°C across –40°C to +125°C. The output is linear and proportional to die temperature (not ambient), and self-heating effects are accounted for in the specified slope. No external calibration is needed for basic thermal monitoring when using the MAX6176BASA+T in its intended operating conditions.
Can the output voltage of the MAX6176BASA+T be adjusted, and if so, how?
Yes, the MAX6176BASA+T output voltage can be trimmed ±6% using the TRIM pin. Connect a resistive divider (e.g., 50kΩ potentiometer) between OUT and GND, with the wiper connected to TRIM. The output change follows ∆VOUT = 2 × (VTRIM – VOUT/2) × k, where k ≈ ±6%. This allows field calibration without hardware changes - a feature not found in most competing 10V references like REF5010IDR or ADR4510BRZ.
Is the MAX6176BASA+T qualified for automotive applications?
The MAX6176BASA+T is part of the MAX6173–MAX6177 family, which includes AEC-Q100 qualified variants (designated with /V suffix). While the MAX6176BASA+T itself is not explicitly marked /V in the ordering information provided, its specifications - including –40°C to +125°C operation, 3ppm/°C tempco, and automotive-grade package - align with AEC-Q100 requirements. For certified automotive use, confirm /V suffix availability with Maxim/Analog Devices or authorized distributors.
