Product details
Overview
MAX6192AESA+T 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 sourcing/sinking, and is used in high-accuracy ADC/DAC biasing, portable instrumentation, and industrial process control systems requiring stable low-power references.
For engineers reviewing the MAX6192AESA+T datasheet, MAX6192AESA+T pinout, MAX6192AESA+T application, or MAX6192AESA+T equivalent, key selection criteria include initial accuracy vs. temperature drift trade-offs, dropout behavior at 500µA load, capacitive-load stability up to 2.2nF, and compatibility with battery-powered 3V/5V systems where supply current immunity to VIN variation is critical.
Technical Context
The MAX6192AESA+T 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) with only 100mV dropout at full load and 0.14µV/µA load regulation.
Internally compensated for fast settling (85µs to 0.1%), it remains stable with capacitive loads from 0 to 2.2nF and exhibits 82dB ripple rejection at 120Hz. Supply current varies by only 0.8µA/V across its input range, making it highly immune to VIN fluctuations - a key differentiator from shunt-mode references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±2mV (guaranteed initial accuracy at +25°C) |
| Temp Coefficient | 4ppm/°C max (ensures ≤±100µV drift over -40°C to +85°C) |
| Quiescent Current | 35µA max (enables >10-year battery life in µA-level systems) |
| Dropout Voltage | 100mV at 500µA load (supports operation down to 2.6V input in 2.5V systems) |
| Load Regulation | 0.14µV/µA (maintains output stability under dynamic load shifts) |
| Line Regulation | 15µV/V (minimizes output shift during supply rail variation) |
| Noise (0.1–10Hz) | 125µVRMS (low enough for 16-bit+ precision data conversion) |
Pinout & Package
MAX6192AESA+T is housed in an 8-pin SO (Small Outline) package, RoHS-compliant and lead(Pb)-free. Pin 1 is OUT, Pin 2 is IN, Pin 4 is GND; Pins 1, 3, 5, 7, and 8 are No Connect (N.C.). The package is optimized for surface-mount assembly and thermal performance in space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 8 | N.C. | No internal connection - must remain unconnected per design; no routing or grounding required |
| 2 | IN | Supply input terminal; accepts 2.7V to 12.6V; requires local decoupling for noise-sensitive applications |
| 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 <100mV dropout |
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 bandgap nonlinearity, reducing temperature-induced error across full operating range |
| Capacitive-load stability (0–2.2nF) | Eliminates need for output capacitor in space-critical designs while maintaining stability under all load conditions |
| Supply-current immunity (0.8µA/V) | Ensures consistent power draw regardless of input rail variation - critical for battery voltage decay compensation |
| Bidirectional load capability (±500µA) | Supports both sourcing and sinking in active filter biasing, DAC reference, and sensor excitation circuits |
Applications
| Hand-Held Instruments | Analog-to-Digital Converters |
|---|---|

| Industrial Process Control | Precision 3V/5V Systems |
Use Scenario: 4–20mA transmitter modules and PLC analog I/O cards operating in harsh factory environments. IC Role / Device Role / Timing Role: Reference source for voltage-controlled current generation and sensor signal conditioning. Use Value: ±500µA load drive handles op-amp bias currents and DAC feedback paths; long-term stability (50ppm/1000hrs) reduces recalibration frequency. |

IC Role / Device Role / Timing Role: Precision reference for LDO feedback networks, MCU VREF inputs, and voltage-monitoring comparators. Use Value: 100mV dropout allows operation with minimal headroom - e.g., 2.6V input sustains 2.500V output at full 500µA load in 3V systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3425BRMZ | 2.5V ±1.5mV initial accuracy, 3ppm/°C max tempco, 3.5µA typical supply current (higher than MAX6192AESA+T's 27–35µA range) | Lower quiescent current but lower load drive (10mA max sink/source); not rated for ±500µA bidirectional operation | Select ADR3425BRMZ when ultra-low power dominates over load flexibility; verify stability with target capacitive load. |
| REF5025IDR | 2.5V ±0.5mV initial accuracy, 3ppm/°C max tempco, 950µA typical supply current, 10mA load drive | Higher accuracy and drive, but 27× higher quiescent current - unsuitable for battery operation | Select REF5025IDR only in mains-powered systems requiring highest initial accuracy and robust load handling; avoid in portable designs. |
Compared with ADR3425BRMZ and REF5025IDR, the MAX6192AESA+T uniquely balances micropower operation (≤35µA), ±500µA bidirectional load support, and 4ppm/°C tempco - making it optimal for space- and energy-constrained precision analog systems where moderate load drive and low drift are jointly required.

FAQ
What is the guaranteed initial accuracy of the MAX6192AESA+T?
The MAX6192AESA+T guarantees ±2mV initial accuracy at +25°C, corresponding to ±0.08% of its 2.500V nominal output. This specification is laser-trimmed and tested across the full -40°C to +85°C operating temperature range, ensuring consistent performance without field calibration.
Does the MAX6192AESA+T require an output capacitor for stability?
No, the MAX6192AESA+T is internally compensated and stable with capacitive loads from 0 to 2.2nF. An output capacitor is optional and only recommended in applications subject to rapid load or supply transients - where it improves transient response and reduces overshoot/undershoot.
What is the minimum input voltage required for the MAX6192AESA+T to maintain regulation?
The MAX6192AESA+T requires a minimum input voltage of (VOUT + 0.2V), i.e., 2.7V, to maintain regulation at full 500µA load. At lighter loads, dropout decreases - e.g., 100mV at 500µA - allowing reliable operation even as battery voltage declines in portable systems.
Can the MAX6192AESA+T both source and sink current?
Yes, the MAX6192AESA+T is fully bidirectional: it can source 0 to +500µA and sink -500µA to 0, with guaranteed load regulation of 0.14µV/µA. This enables use in active filter biasing, DAC reference buffering, and sensor excitation circuits where current flows in either direction.
How does the supply current of the MAX6192AESA+T vary with input voltage?
The MAX6192AESA+T exhibits exceptional supply-current immunity: quiescent current varies by only 0.8µA/V across its input range (2.7V to 12.6V). This means total supply current stays within 27µA to 35µA regardless of VIN - a critical advantage over shunt-mode references whose current scales linearly with supply voltage.
