Product details
Overview
MAX6192AESA from Maxim Integrated is a precision, micropower, low-dropout series-mode bandgap voltage reference delivering 2.500V ±2mV initial accuracy, 4ppm/°C max temperature coefficient, and 35µA max quiescent supply current. It operates from (VOUT + 0.2V) to 12.6V input, supports ±500µA load current with 100mV dropout at 500µA, and is used in high-accuracy ADC/DAC biasing and portable instrumentation power rails.
For engineers reviewing the MAX6192AESA datasheet, MAX6192AESA pinout, MAX6192AESA application, or MAX6192AESA equivalent, key selection criteria include initial output voltage tolerance, long-term stability (50ppm/1000hrs), capacitive-load stability up to 2.2nF, and line regulation of 15µV/V - all critical for precision analog signal chains in battery-powered systems.
Technical Context
The MAX6192AESA employs a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve <5ppm/°C temperature coefficient and ±2mV initial accuracy. Its series-mode architecture enables bidirectional load current (±500µA) while maintaining low dropout (100mV @ 500µA) and near-constant 35µA supply current across input voltage variations.
Internally compensated for stability with capacitive loads up to 2.2nF, it achieves 85µs turn-on settling time to 0.1% and delivers 125µVRMS (10Hz–10kHz) noise performance. Ripple rejection is 82dB at 120Hz, and output impedance remains below 1Ω up to 10kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±2mV (guaranteed initial accuracy over -40°C to +85°C) |
| Temp Coefficient | 4ppm/°C max (ensures ≤±100µV drift over full industrial temperature range) |
| Quiescent Current | 35µA max (enables >10-year battery life in µA-level standby systems) |
| Dropout Voltage | 100mV @ 500µA load (supports operation from 2.6V supply in 2.5V systems) |
| Load Regulation | 0.14µV/µA (≤70µV shift across full ±500µA load range) |
| Line Regulation | 15µV/V (≤150µV shift over 10V input variation) |
| Noise (10Hz–10kHz) | 125µVRMS (low enough for 16-bit+ SAR ADC reference without external filtering) |
Pinout & Package
MAX6192AESA is housed in an 8-pin SO (Small Outline) package with RoHS-compliant lead-free finish. Pin 1 is OUT, Pin 2 is IN, Pin 4 is GND; Pins 1, 3, 5, 7, and 8 are No Connect (N.C.) and must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | N.C. | No internal connection; must be left floating or tied to GND per layout best practice - no electrical function |
| 2 | IN | Positive supply input; requires ≥2.7V (VOUT + 0.2V) for regulation; tolerant to 13.5V absolute max |
| 4 | GND | Analog ground reference; must be connected to clean system ground plane with low-impedance path |
| 6 | OUT | Precision 2.500V reference output; capable of sourcing/sinking ±500µA with minimal voltage shift |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed thin-film resistors | Enables ±2mV initial accuracy and <5ppm/°C tempco without external calibration |
| Curvature-correction circuit | Compensates second-order thermal effects to minimize parabolic VOUT vs. temperature error |
| Capacitive-load stability | Stable with 0–2.2nF output capacitance - eliminates need for minimum COUT in space-constrained designs |
| Bidirectional load capability | Sinks or sources up to 500µA while maintaining regulation - supports active filter bias and DAC reference sink paths |
| Low line/load regulation | 15µV/V line and 0.14µV/µA load regulation enable direct use in high-resolution data acquisition front-ends |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3425BRMZ | 2.5V ±1.5mV initial accuracy, 3ppm/°C max tempco, 3.5µA typical quiescent current (lower power but higher noise: 200µVRMS) | Lower supply current suits ultra-low-power IoT nodes; higher noise limits use in >14-bit ADCs | Select ADR3425BRMZ when sub-10µA average current dominates design priority and noise budget allows ≥200µVRMS |

FAQ
What is the maximum load current supported by the MAX6192AESA while maintaining regulation?
The MAX6192AESA supports ±500µA load current - meaning it can both source up to +500µA and sink up to -500µA while maintaining output voltage within specified accuracy limits. At 500µA sourcing, dropout is guaranteed at 100mV; performance is validated across the full industrial temperature range (-40°C to +85°C). This bidirectional capability makes MAX6192AESA suitable for driving active filters and reference inputs that require sink current.
Does the MAX6192AESA require an external output capacitor for stability?
No, the MAX6192AESA is internally compensated and stable with output capacitance ranging from 0 to 2.2nF. An external capacitor is optional and only recommended in applications subject to large load or supply transients - where it reduces overshoot/undershoot and improves transient response. For space-constrained PCBs or zero-capacitance designs, MAX6192AESA operates reliably without any output capacitor.
What is the supply voltage range for reliable operation of the MAX6192AESA?
The MAX6192AESA operates with a supply voltage from (VOUT + 0.2V) = 2.7V minimum to 12.6V maximum. Below 2.7V, regulation is not guaranteed; above 12.6V risks damage (absolute max is 13.5V). The device draws only 35µA quiescent current across this range, with supply current variation limited to 2µA/V - enabling stable performance even with noisy or drifting supply rails.
How does the MAX6192AESA compare to the MAX6192BESA and MAX6192CESA in accuracy and tempco?
The MAX6192AESA offers the highest grade: ±2mV initial accuracy and 4ppm/°C max temperature coefficient. In contrast, MAX6192BESA provides ±5mV / 10ppm/°C, and MAX6192CESA provides ±10mV / 25ppm/°C. All share identical pinout, package (8-SO), and electrical behavior outside these graded specs - allowing design reuse across accuracy tiers by selecting the appropriate variant during BOM finalization.
Is the MAX6192AESA RoHS-compliant and lead-free?
Yes, the MAX6192AESA carries the "+" suffix (as shown in ordering code MAX6192AESA+), which explicitly denotes a lead(Pb)-free and RoHS-compliant package. It uses standard SnAgCu (SAC305) solder-compatible terminations and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements for unlimited floor life at ≤30°C/85% RH.
