Product details
Overview
The MAX6165AESA+T from Maxim Integrated is a precision, low-dropout, micropower series voltage reference delivering a stable 5.000V 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 + 0.2V (5.2V) to 12.6V, and draws only 100µA typical supply current - ideal for high-accuracy ADC biasing in battery-powered instrumentation.
For engineers reviewing the MAX6165AESA+T datasheet, MAX6165AESA+T pinout, MAX6165AESA+T application, or MAX6165AESA+T equivalent, key selection criteria include its 5.000V output tolerance, ultra-low 5ppm/°C drift, dropout voltage ≤200mV at 1mA, 60µVp-p (0.1–10Hz) noise, and SO-8 package compatibility with space-constrained portable designs.
Technical Context
This device uses a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve precision performance without external compensation. Its BiCMOS process enables stable operation with 1µF capacitive loads while eliminating the need for an external output capacitor - reducing board area and component count.
As a three-terminal series-mode reference, it delivers supply-current independence (≤8µA/V variation) and avoids the inefficiency of shunt-mode alternatives. Input voltage range starts at VOUT + 0.2V, supporting low-headroom operation in modern low-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±2mV at +25°C - ensures direct compatibility with 5V ADC reference inputs without calibration |
| Temp Coefficient | 5ppm/°C max - limits full-range drift to ±1.5mV over -40°C to +85°C |
| Dropout Voltage | 200mV max at 1mA load - enables operation from 5.2V supply in 5V systems |
| Noise (0.1–10Hz) | 60µVp-p - preserves SNR in 16-bit+ data acquisition circuits |
| Supply Current | 100µA typical - extends battery life in portable meters and sensors |
| Load Regulation | 0.9mV/mA sourcing - maintains stability across 0–5mA load variations |
| Ripple Rejection | 65dB at 120Hz - suppresses power-supply ripple in noisy environments |
Pinout & Package
MAX6165AESA+T is housed in an 8-pin SO (Small Outline) package with exposed pad (RoHS-compliant, lead-free). Pins 1, 3, 5, 7, and 8 are No Connect (N.C.); Pin 2 is IN; Pin 4 is GND; Pin 6 is OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 2) | Input voltage supply terminal | Accepts 5.2V–12.6V; requires local 0.1µF ceramic bypass for optimal line transient response |
| GND (Pin 4) | Reference ground connection | Must be connected to clean system ground plane; serves as return path for load and quiescent current |
| OUT (Pin 6) | Precision reference output | Delivers regulated 5.000V; stable with ≥1µF capacitive loads but does not require external capacitor |
| N.C. (Pins 1,3,5,7,8) | No internal connection | May be left unconnected or tied to GND for mechanical stability; no electrical function |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050IDR | 5.0V output, 3ppm/°C max tempco, 50µVp-p noise, SO-8, but requires 1.5mA supply current | Higher accuracy and lower noise, but 15× higher quiescent current limits use in ultra-low-power systems | Select REF5050IDR when ultimate drift performance outweighs battery-life constraints |
| ADR4550BRZ | 5.0V output, 3ppm/°C max tempco, 50µVp-p noise, SO-8, 950µA supply current, includes enable pin | Superior drift/noise specs but significantly higher supply current and larger footprint (SOIC-8 vs. SO-8 with exposed pad) | Choose ADR4550BRZ for lab-grade instrumentation where power is not constrained |
Compared with REF5050IDR and ADR4550BRZ, the MAX6165AESA+T trades minor drift/noise margin for 10× lower supply current and smaller thermal footprint - making it optimal for portable, battery-sensitive designs where 5ppm/°C and 60µVp-p noise meet system requirements.

FAQ
What is the maximum load current the MAX6165AESA+T can source?
The MAX6165AESA+T can source up to 5mA while maintaining specified output voltage accuracy and regulation. This capability allows direct driving of ADC reference inputs, op-amp bias networks, and small sensor excitation circuits without external buffering. At 5mA load, the load regulation is guaranteed at ≤0.9mV/mA, resulting in ≤4.5mV total deviation from nominal 5.000V output.
Does the MAX6165AESA+T require an external output capacitor for stability?
No, the MAX6165AESA+T is internally compensated and does not require an external output capacitor for frequency stability. It remains stable with capacitive loads up to 1µF, and many applications operate reliably with no output capacitor - saving PCB area and BOM cost. An optional 0.1µF–1µF ceramic capacitor may be added to improve transient response under step-load conditions.
What is the minimum input voltage required for proper operation of the MAX6165AESA+T?
The minimum input voltage for the MAX6165AESA+T is VOUT + 0.2V = 5.2V, as specified in the electrical characteristics table. Operation below this voltage results in increased dropout and potential loss of regulation. The device supports input voltages up to 12.6V and maintains line regulation performance across this full range, with typical variation of ≤400µV/V.
How does the MAX6165AESA+T compare to shunt-mode voltage references in terms of efficiency?
The MAX6165AESA+T is a series-mode reference with supply current virtually independent of input voltage (≤8µA/V variation), drawing only 100µA typical regardless of VIN. In contrast, shunt-mode references require a series resistor and draw current proportional to input voltage - wasting power, especially at higher VIN. This makes the MAX6165AESA+T significantly more efficient in battery-powered systems and reduces thermal load on PCBs.
Is the MAX6165AESA+T RoHS-compliant and lead-free?
Yes, the MAX6165AESA+T is RoHS-compliant and lead-free, indicated by the "+" suffix in the part number per Maxim's ordering guide. It uses a lead(Pb)-free SO-8 package with standard JEDEC land pattern (outline 21-0041, land pattern 90-0096) and meets all applicable environmental compliance requirements for commercial and industrial applications.
