Product details
Overview
MAX6143AASA10 from Maxim Integrated is a high-precision, low-noise voltage reference with integrated temperature sensor output. It delivers a stable +10.000V reference (±0.05% initial accuracy, 3ppm/°C max tempco) and a linear TEMP output (630mV at +25°C, 2.1mV/°C), enabling simultaneous precision referencing and die-temperature monitoring in space-constrained industrial and automotive systems.
For engineers reviewing the MAX6143AASA10 datasheet, MAX6143AASA10 pinout, MAX6143AASA10 application, or MAX6143AASA10 equivalent, this device supports high-resolution ADC/DAC biasing, threshold detection with thermal compensation, and battery-powered instrumentation requiring ultra-low shutdown current (0.01µA) and no external output capacitor.
Technical Context
The MAX6143AASA10 uses bandgap-based architecture with proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve 3ppm/°C temperature coefficient over –40°C to +125°C. Its TRIM input enables ±6% output adjustment via external resistive divider, while the TEMP pin provides a ratiometric voltage proportional to junction temperature.
It operates from (VOUT + 2V) to +40V input (i.e., 12V–40V for 10V output), draws 340µA quiescent current (max 700µA over temp), sources up to 30mA, sinks 2mA, and features active-low SHDN with 0.8V logic threshold - all in an 8-pin SO package rated for automotive temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +10.000V (±0.05% initial accuracy at +25°C; 9.995V–10.005V) |
| Tempco | 3ppm/°C max (–40°C to +125°C); ensures ≤±0.003V drift over full range |
| Noise (0.1–10Hz) | 18µVP-P typical; critical for 16+ bit ADC stability |
| Supply Range | 12V to +40V; supports wide-input industrial rails without external regulators |

Pinout & Package
MAX6143AASA10 is housed in an 8-pin SO (SOIC-N) package per JEDEC MS-012, 150-mil body width, with exposed pad not present. Pin 1 and Pin 8 are internally connected (do not route externally).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 2) | Positive supply input | Accepts 12V–40V; requires ≥2V headroom above VOUT for regulation |
| TEMP (Pin 3) | Digital-temperature transducer output | Provides 630mV @ +25°C, 2.1mV/°C slope; high-impedance, must not be loaded |
| GND (Pin 4) | Analog ground reference | Common return for IN, OUT, SHDN, TRIM, TEMP; separate from digital ground in mixed-signal layouts |
| TRIM (Pin 5) | Voltage-adjustment interface | Connects to center tap of resistive divider (e.g., 50kΩ pot) between OUT and GND for ±6% fine-tuning |
| OUT (Pin 6) | Precision reference output | +10.000V source/sink node; stable with 0–100µF capacitive loads; no bypass cap required |
| SHDN (Pin 7) | Active-low enable control | Logic-low (<0.8V) disables output and reduces IIN to 0.01µA; tie to IN for always-on operation |

FAQ
What is the guaranteed initial accuracy of the MAX6143AASA10?
The MAX6143AASA10 has a guaranteed initial accuracy of ±0.05% at +25°C, meaning its output voltage falls within 9.995V to 10.005V under no-load conditions at room temperature. This specification is production-tested and applies across the full automotive temperature range when combined with its 3ppm/°C temperature coefficient.
Does the MAX6143AASA10 require an output bypass capacitor?
No, the MAX6143AASA10 does not require an output bypass capacitor for stability. It is designed to remain stable with capacitive loads ranging from 0 to 100µF, eliminating the need for external components and saving PCB area - a key advantage in space-constrained applications like handheld instruments and automotive modules.
How is the TEMP output of the MAX6143AASA10 used?
TEMP on the MAX6143AASA10 outputs a voltage proportional to die temperature: 630mV at +25°C with a slope of 2.1mV/°C. It is intended for high-impedance measurement only - loading it degrades accuracy. Used with a microcontroller's ADC, it enables real-time junction temperature monitoring for thermal compensation or safety shutdown without adding a discrete sensor.
What is the minimum input voltage required for the MAX6143AASA10 to regulate at 10V?
The MAX6143AASA10 requires a minimum input voltage of (VOUT + 2V), which is 12V for its +10V output. Operation below 12V will result in dropout and loss of regulation. The device supports inputs up to +40V, making it compatible with wide-range industrial and automotive supplies.
Can the output voltage of the MAX6143AASA10 be adjusted, and if so, how?
Yes, the MAX6143AASA10 output can be trimmed ±6% using the TRIM pin. Connect a resistive divider (e.g., 50kΩ potentiometer) between OUT and GND, with the wiper tied to TRIM. The output voltage changes linearly with TRIM voltage, enabling system-level calibration or gain adjustment without modifying the main reference path.
