Product details
Overview
MAX6175BASA+T from Maxim Integrated is a high-precision, low-noise +5.0V voltage reference with integrated temperature sensor output, 3ppm/°C max temperature coefficient, ±0.1% initial accuracy, and 9µVRMS (10Hz–1kHz) noise performance. It operates from 7.0V to 40V input, sources up to 30mA, and supports automotive-grade operation from −40°C to +125°C - ideal for precision ADC/DAC biasing in industrial data acquisition systems.
For engineers reviewing the MAX6175BASA+T datasheet, MAX6175BASA+T pinout, MAX6175BASA+T application, or MAX6175BASA+T equivalent, key selection criteria include its guaranteed 3ppm/°C TC over full temperature range, TRIM-adjustable output (±6% range), TEMP output linearity (2.1mV/°C), no-output-capacitor stability, and AEC-Q100-compatibility of /V variants.
Technical Context
The MAX6175BASA+T uses curvature-corrected bandgap architecture with laser-trimmed thin-film resistors to achieve ultra-low temperature drift and tight initial tolerance. Its internal TEMP output is directly proportional to die temperature (2.1mV/°C), enabling on-chip thermal monitoring without external sensors.
It features active 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 - simplifying layout in space-constrained, high-reliability applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +5.0V nominal, ±0.1% initial accuracy (4.995V to 5.005V at +25°C) |
| Tempco (TCVOUT) | 3ppm/°C maximum over −40°C to +125°C - ensures ≤0.5mV drift across full automotive range |
| Noise (10Hz–1kHz) | 14.5µVRMS - enables <18-bit effective resolution in precision SAR ADCs |
| Supply Current | 320µA typical, 700µA max at +125°C - supports low-power battery-backed instrumentation |
| Input Voltage Range | +7.0V to +40V - accommodates wide-input industrial supplies and unregulated rails |
| TEMP Output | 630mV at +25°C, 2.1mV/°C slope - provides calibrated die-temperature sensing with ±1.5°C accuracy |
| Load Drive | Sources 30mA / sinks 2mA - directly drives ADC reference inputs and small analog circuitry |
Pinout & Package
MAX6175BASA+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 | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | I.C. | Internally connected - must remain unconnected on PCB |
| 2 | IN | Positive supply input (7.0V to 40V); requires 0.1µF ceramic decoupling near pin |
| 3 | TEMP | Temperature-proportional analog output (630mV @ +25°C, 2.1mV/°C) |
| 4 | GND | Analog ground reference - connect to clean system ground plane |
| 5 | TRIM | Voltage divider node for ±6% output adjustment; leave open for factory preset |
| 6 | OUT | +5.0V precision reference output - stable without external capacitor |
| 7 | N.C. | No internal connection - electrically floating; may be left unconnected or tied to GND |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050IDR | +5.0V output, 3ppm/°C max tempco, but higher 550µA supply current and no TEMP output | Lacks integrated temperature sensing; requires external thermal monitoring | Choose when TEMP functionality is unnecessary and lower quiescent current is not critical |
| ADR4550BRZ | +5.0V output, 3ppm/°C max tempco, 1.8µVP-P (0.1–10Hz) noise, but no TRIM or TEMP pins | Superior low-frequency noise, but no adjustability or thermal telemetry capability | Prefer for ultra-low-noise metrology where trimming and die-temp feedback are omitted |
Compared with REF5050IDR and ADR4550BRZ, MAX6175BASA+T uniquely integrates trimmability, temperature telemetry, and low quiescent current in a single 8-pin SO package - making it optimal for space-constrained, thermally aware embedded systems requiring both precision and diagnostics.

FAQ
What is the guaranteed initial accuracy of the MAX6175BASA+T?
The MAX6175BASA+T guarantees ±0.1% initial output voltage accuracy at +25°C, corresponding to a 4.995V to 5.005V range for its +5.0V nominal output. This specification is verified during 100% production testing and applies across all units shipped as MAX6175BASA+T.
Does the MAX6175BASA+T require an output capacitor for stability?
No - the MAX6175BASA+T is internally compensated and stable without any output capacitor. It remains stable with capacitive loads up to 100µF, allowing designers to omit the output cap entirely or add one solely for transient response improvement, not stability.
How is the TEMP output of the MAX6175BASA+T calibrated?
The MAX6175BASA+T TEMP pin delivers 630mV at +25°C with a slope of 2.1mV/°C across −40°C to +125°C. Calibration is factory-trimmed; no user adjustment is needed. Self-heating effects are minimal under typical load conditions, preserving measurement fidelity.
Can the output voltage of the MAX6175BASA+T be adjusted, and if so, how?
Yes - the MAX6175BASA+T includes a TRIM pin enabling ±6% output adjustment via a resistive divider between OUT, TRIM, and GND. With a 50kΩ potentiometer, the output can be fine-tuned across ~4.7V to 5.3V while maintaining specified tempco and noise performance.
What is the maximum supply voltage the MAX6175BASA+T can tolerate?
The MAX6175BASA+T supports an absolute maximum input voltage of +42V (IN to GND), with guaranteed operation from +7.0V to +40V. Operation below +7.0V is not specified; dropout voltage increases with load current, reaching ~2.5V at 30mA source current.
