Product details
Overview
MAX6195AESA+ from Maxim Integrated is a precision, micropower, low-dropout series-mode bandgap voltage reference delivering 5.000V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and 35µA max quiescent supply current. It operates from (VOUT + 0.2V) to 12.6V input, supports ±500µA load sourcing/sinking, and is used in high-accuracy ADC/DAC biasing and portable instrumentation.
For engineers reviewing the MAX6195AESA+ datasheet, MAX6195AESA+ pinout, MAX6195AESA+ application, or MAX6195AESA+ equivalent, key selection criteria include guaranteed 5.000V output tolerance, ultra-low 35µA supply current across input voltage variation, 100mV dropout at 500µA, 0.17µV/µA load regulation, and stability with up to 2.2nF capacitive load.
Technical Context
The MAX6195AESA+ employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve <5ppm/°C temperature coefficient and ±2mV initial accuracy over -40°C to +85°C. Its series-mode architecture enables bidirectional 500µA load current capability without external pass components.
Internally compensated for fast settling (220µs to 0.1%), it maintains stability with capacitive loads from 0 to 2.2nF and exhibits 8µV/V line regulation and 0.17µV/µA load regulation - critical for precision data conversion systems where supply and load transients must not perturb reference integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±2mV (guaranteed initial accuracy at +25°C; enables direct replacement of 5V references in 12-bit+ ADC/DAC systems) |
| Temp Coefficient | ≤5ppm/°C (max over -40°C to +85°C; ensures ≤0.25mV drift across full industrial range) |
| Quiescent Current | ≤35µA (max; draws near-constant current regardless of input voltage, optimizing battery life in portable instruments) |
| Dropout Voltage | 100mV at 500µA load (enables operation from 5.1V supply in 5V systems with margin) |
| Load Regulation | 0.17µV/µA (max; contributes ≤85µV error over full ±500µA load range) |
| Line Regulation | 25µV/V (max; limits supply-induced error to ≤250µV over 10V input swing) |
| Noise (0.1–10Hz) | 240µVRMS (specifies low-frequency noise floor critical for high-resolution DC measurements) |
Pinout & Package
MAX6195AESA+ is housed in an 8-pin SO (Small Outline) package, RoHS-compliant and rated for -40°C to +85°C operation. Pin 1 is OUT, Pin 2 is IN, Pin 4 is GND; Pins 1,3,5,7,8 are No Connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | N.C. | No internal connection; must be left unconnected or tied to GND per layout best practice - no routing or loading permitted |
| 2 | IN | Supply input terminal; accepts 5.2V to 12.6V; requires local 0.1µF bypass capacitor to GND |
| 4 | GND | Analog ground reference; must connect to clean system ground plane with low-inductance path |
| 6 | OUT | Precision 5.000V reference output; capable of sourcing/sinking ±500µA; stable with 0–2.2nF capacitive load |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±2mV initial accuracy and <5ppm/°C tempco without external calibration |
| Proprietary curvature-correction circuit | Compensates second-order thermal effects, achieving flat VOUT vs. temperature response |
| Series-mode architecture | Eliminates need for external series resistor; supplies load current only when required - no wasted bias current |
| Internal compensation | Guarantees stability with 0–2.2nF output capacitance, removing need for external compensation network |
| Bidirectional 500µA load drive | Supports both sourcing and sinking, enabling use in buffered reference, DAC gain-setting, and active filter applications |

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, 950µA quiescent current, SO-8 package | Higher power consumption; better tempco but unsuitable for battery operation | Select REF5050IDR only when ultra-low tempco outweighs power budget constraints |
| ADR4550BRZ | 5.0V output, 3ppm/°C max tempco, 950µA quiescent current, SO-8 package, higher long-term stability (15ppm/1000hrs) | Not micropower; requires >10× more supply current; superior aging performance | Choose ADR4550BRZ for mains-powered metrology systems where aging dominates design lifetime |
Compared with REF5050IDR and ADR4550BRZ, the MAX6195AESA+ uniquely delivers 5.000V precision with sub-35µA supply current - making it the only viable option for space-constrained, battery-operated instrumentation requiring both accuracy and energy efficiency.

FAQ
What is the guaranteed initial accuracy of the MAX6195AESA+ at +25°C?
The MAX6195AESA+ guarantees ±2mV initial output voltage accuracy at +25°C, corresponding to ±0.04% of its 5.000V nominal output. This specification is laser-trimmed and tested per Maxim's production flow, ensuring compliance across all units shipped as MAX6195AESA+.
Does the MAX6195AESA+ require an external output capacitor for stability?
No, the MAX6195AESA+ is internally compensated and stable with capacitive loads from 0 to 2.2nF. An external capacitor is optional and used only to improve transient response - not required for loop stability. Layouts can omit it to save board space when transients are minimal.
What is the minimum input voltage required for the MAX6195AESA+ to maintain regulation at full load?
The MAX6195AESA+ requires a minimum input voltage of VOUT + 0.2V = 5.2V to maintain regulation at 500µA load current. Its 100mV dropout voltage is specified at 500µA, so operation below 5.2V risks loss of regulation and increased output error.
Can the MAX6195AESA+ sink current, and if so, how much?
Yes, the MAX6195AESA+ can both source and sink up to 500µA while maintaining output accuracy. Its series-mode architecture supports bidirectional load current, enabling use in active filter feedback paths, DAC gain-setting networks, and precision current-source biasing circuits.
Is the MAX6195AESA+ compatible with standard SO-8 reflow profiles?
Yes, the MAX6195AESA+ uses a lead(Pb)-free RoHS-compliant SO-8 package qualified for standard Pb-free reflow soldering (peak temperature +260°C, per JEDEC J-STD-020). The device's thermal characteristics and package construction meet IPC-A-610 Class 2/3 requirements for automated assembly.
