Product details
Overview
MAX6162AESA+ from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering a stable 2.048V output with ±2mV initial accuracy and 5ppm/°C max temperature coefficient over -40°C to +85°C. It sources up to 5mA, sinks 2mA, operates from (VOUT + 200mV) to 12.6V, and requires no external compensation capacitor-ideal for high-accuracy ADC biasing in portable instrumentation.
For engineers reviewing the MAX6162AESA+ datasheet, MAX6162AESA+ pinout, MAX6162AESA+ application, or MAX6162AESA+ equivalent, key selection criteria include its 2.048V output voltage matched to 12-bit DAC/ADC full-scale ranges, ultra-low 100μA quiescent current, 200mV max dropout at 1mA, stability with 1μF loads, and SO-8 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX6162AESA+ employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve 5ppm/°C max TCVOUT and ±2mV initial accuracy. Its internal compensation eliminates need for external capacitors, and supply current varies only 3.4–8.0μA/V across input voltage range.
As a three-terminal series-mode reference, it regulates output referenced to GND, supports sourcing and sinking load currents, and maintains performance under line/load transients-enabling direct replacement of discrete Zener/shunt references in precision analog signal chains without redesigning bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V (±2mV at +25°C); precisely matches 12-bit 4096-step full-scale reference for SAR and sigma-delta ADCs |
| Temp Coefficient | 5ppm/°C (max); ensures ≤0.42mV drift over -40°C to +85°C ambient, critical for field-deployed sensors |
| Quiescent Current | 100μA (typ); enables >1-year battery life in coin-cell-powered data loggers drawing <10μA average system current |
| Dropout Voltage | 200mV (max at 1mA); allows operation from 2.25V supply in single Li-ion or dual alkaline systems |
| Load Regulation | 0.9mV/mA (sourcing); limits output shift to <4.5mV across full 5mA load range-within 0.22% of 2.048V |
| Noise (0.1–10Hz) | 22µVP-P; contributes <0.001% RMS error in 20-bit measurement systems with proper filtering |
| Ripple Rejection | 78dB at 120Hz; attenuates AC line noise on shared DC rails by 79×, preserving reference integrity |
Pinout & Package
MAX6162AESA+ is housed in an 8-pin SO (Small Outline) package with exposed pad (RoHS-compliant, lead-free). Pin 1, 3, 5, 7, and 8 are No Connect (N.C.), internally unconnected. Functional terminals are isolated to minimize parasitic coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2 (IN) | Input Supply Terminal | Accepts 2.248V to 12.6V; must be decoupled with 0.1µF ceramic near pin for optimal line-transient immunity |
| 4 (GND) | Analog Ground Reference | Low-impedance return path for reference core; requires dedicated ground plane connection to avoid PSRR degradation |
| 6 (OUT) | Precision Output Terminal | Delivers regulated 2.048V; stable with 0–1µF capacitive loads; no external capacitor required for stability |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±2mV initial accuracy and 5ppm/°C TCVOUT without post-package calibration |
| Internally compensated architecture | Eliminates external compensation capacitor-reduces BOM count and saves ≥2mm² PCB area |
| Supply-current independence | Draws only 100μA ±8μA/V across 2.25–12.6V input range, maximizing battery runtime |
| High-output-current capability | Sources 5mA / sinks 2mA-drives ADC reference inputs, op-amp bias networks, and DAC buffers directly |
| Stable with capacitive loads | Remains stable with 0–1µF output capacitance, simplifying layout for noisy mixed-signal environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5020IDR | 2.048V output, 3ppm/°C max TCVOUT, 50μA IQ, SO-8; requires 1μF output cap for stability | Better tempco but higher external component count; lower quiescent current suits ultra-low-power sleep modes | Select REF5020IDR when <3ppm/°C drift is mandatory and board area allows 1μF capacitor |
| ADR4520BRZ | 2.048V output, 3ppm/°C max TCVOUT, 950μA IQ, SO-8; needs 10μF output cap, higher drive strength (10mA) | Higher power consumption; superior long-term stability (15ppm/1000hr vs. 80ppm/1000hr) | Choose ADR4520BRZ for lab-grade equipment where stability outweighs battery life constraints |
Compared with REF5020IDR and ADR4520BRZ, MAX6162AESA+ offers the best balance of ultra-low quiescent current (100μA), zero external capacitor requirement, and production-proven 5ppm/°C performance-making it optimal for cost-sensitive, space-constrained portable instruments where moderate tempco suffices.

FAQ
What is the output voltage tolerance and temperature coefficient of the MAX6162AESA+?
The MAX6162AESA+ has a nominal output voltage of 2.048V with ±2mV initial accuracy at +25°C and a maximum temperature coefficient of 5ppm/°C over the -40°C to +85°C operating range. These specifications are guaranteed per the datasheet's electrical characteristics table for the MAX6162A grade, ensuring predictable drift behavior in precision analog circuits.
Does the MAX6162AESA+ require an external output capacitor for stability?
No, the MAX6162AESA+ does not require an external output capacitor for stability due to its internally compensated architecture. It remains stable with 0–1µF capacitive loads. A 0.1µF ceramic capacitor may be added at the output to improve transient response in dynamic load conditions, but it is optional-not mandatory for loop stability.
What is the minimum input voltage required for the MAX6162AESA+ to maintain regulation?
The MAX6162AESA+ requires a minimum input voltage of VOUT + 200mV = 2.248V to maintain regulation at 1mA load current. Its dropout voltage is specified as 200mV (max) at 1mA, allowing reliable operation from low-voltage sources such as single-cell Li-ion (2.7–4.2V) or dual alkaline (2.4–3.2V) batteries.
Can the MAX6162AESA+ both source and sink load current?
Yes, the MAX6162AESA+ can source up to 5mA and sink up to 2mA of load current. This bidirectional capability enables flexible use in circuits requiring active pull-up/pull-down, such as driving ADC reference inputs, biasing op-amp feedback networks, or interfacing with programmable gain amplifiers-all while maintaining output accuracy within specification.
Is the MAX6162AESA+ RoHS-compliant and what package does it use?
Yes, the MAX6162AESA+ is RoHS-compliant and supplied in an 8-pin SO (Small Outline) package with lead-free finish ("+" suffix denotes RoHS compliance). The package outline is S8+2 (Maxim package code), with land pattern 90-0096 and outline number 21-0041, suitable for standard surface-mount assembly processes.
