Product details
Overview
MAX4292EBL-T from Maxim Integrated is a dual, micropower, rail-to-rail input/output operational amplifier optimized for ultra-low-voltage, high-precision portable systems. It operates from 1.8V to 5.5V single supply (or ±0.9V to ±2.75V dual), draws only 100µA per amplifier, delivers 500kHz gain-bandwidth, achieves 120dB open-loop gain, and features ±200µV input offset voltage - enabling accurate signal conditioning in 2-cell battery-powered instrumentation and sensor interfaces.
For engineers reviewing the MAX4292EBL-T datasheet, MAX4292EBL-T pinout, MAX4292EBL-T application, or MAX4292EBL-T equivalent, key selection criteria include guaranteed 1.8V operation, rail-to-rail I/O swing within 46mV of rails into 2kΩ, 0.017% THD+N at 1kHz, unity-gain stability with ≤100pF capacitive loads, and ultra-small 8-bump UCSP package footprint (1.5mm × 1.5mm).
Technical Context
The MAX4292EBL-T employs a composite NPN/PNP input stage enabling true rail-to-rail common-mode input range (0V to VCC) and crossover-free operation across the full supply range. Its output stage uses complementary push-pull circuitry capable of sourcing/sinking ≥3.5mA while maintaining rail-to-rail swing under 2kΩ load.
It achieves 120dB open-loop gain (RL = 100kΩ), 80dB CMRR and PSRR (VCC = 1.8V), and 500kHz GBWP with 65° phase margin - ensuring stable precision amplification in low-noise, low-power configurations such as sensor front-ends and battery-monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V single supply - supports direct operation from depleted two-cell alkaline (1.8V) or fresh Li-ion (4.2V) without regulation. |
| Quiescent Current | 100µA per amplifier - enables multi-year battery life in always-on portable instrumentation. |
| Gain-Bandwidth Product | 500kHz - sufficient for DC–100Hz sensor signals with >60dB closed-loop gain stability. |
| Input Offset Voltage | ±200µV (max) - ensures <0.5mV error in 2.5V full-scale 12-bit ADC interfaces. |
| Output Swing (2kΩ) | Within 46mV of rails - delivers >98% dynamic range utilization in 1.8V systems. |
| THD + Noise | 0.017% at 1kHz - preserves signal fidelity in audio-grade and precision analog front-ends. |
| Capacitive Load Stability | Unity-gain stable up to 100pF - eliminates need for isolation resistors in most PCB trace and filter capacitor scenarios. |
Pinout & Package
The MAX4292EBL-T is housed in an 8-bump, 1.5mm × 1.5mm ultra chip-scale package (UCSP™) with bottom-side solder bumps. This leadless, wafer-level package minimizes parasitic inductance/capacitance and reduces board area by >70% versus SO-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Bump A1) | OUTA | Output of Amplifier A - drives external load or feedback network; rail-to-rail swing capability critical for low-headroom systems. |
| 2 (Bump B1) | INA− | Inverting input of Amplifier A - matched impedance required to minimize bias-current-induced offset errors. |
| 3 (Bump C1) | INA+ | Noninverting input of Amplifier A - accepts rail-to-rail common-mode signals (0V to VCC) without phase reversal. |
| 4 (Bump A2) | VCC | Positive supply - requires local 100nF bypass capacitor to ground for noise immunity and stability. |
| 5 (Bump B3) | INB− | Inverting input of Amplifier B - electrically isolated from INA−; channel-to-channel isolation >83dB prevents crosstalk in dual-sensor systems. |
| 6 (Bump C3) | INB+ | Noninverting input of Amplifier B - identical rail-to-rail input behavior as INA+; enables independent dual-channel signal conditioning. |
| 7 (Bump A3) | OUTB | Output of Amplifier B - fully independent output stage; no shared internal nodes with OUTA. |
| 8 (Bump B2) | VEE | Negative supply - tied to GND in single-supply mode; establishes reference for rail-to-rail output swing and input common-mode range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Common-mode range extends to both supply rails; output swings to within 46mV of VEE/VCC into 2kΩ - maximizes usable signal range in 1.8V systems. |
| Ultra-Low Supply Current | 100µA per amplifier - enables integration into energy-harvesting and coin-cell-powered devices without compromising battery life. |
| No Phase Reversal on Overdrive | Input stage remains linear even when inputs exceed supply rails - prevents latch-up and output glitches during transient overvoltage events. |
| High Open-Loop Gain | 120dB (RL = 100kΩ) - ensures <0.0025% gain error in unity-gain buffer and precision gain stages. |
| Low Input Offset Drift | 1.2µV/°C - maintains calibration integrity across industrial temperature range (−40°C to +85°C) without active trimming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550µA/amplifier), wider supply range (2.7V–6V), lower GBWP (6.4MHz), larger SO-8 package. | Not suitable for 1.8V operation or ultra-low-power designs; better for higher-speed, higher-supply applications. | Select TLV2462IDR only if >1MHz bandwidth or >2.7V minimum supply is required; avoid for 2-cell battery systems. |
| AD8602ARMZ | Lower input offset (±60µV), higher supply current (160µA/amplifier), same 1.8V min, SO-8 package, no UCSP option. | Superior DC precision but 60% higher current draw; lacks ultra-small footprint for space-constrained wearables. | Choose AD8602ARMZ when offset-critical DC accuracy outweighs size/power constraints; MAX4292EBL-T preferred for miniaturized, long-life designs. |
Compared with TLV2462IDR and AD8602ARMZ, the MAX4292EBL-T uniquely combines 1.8V operation, 100µA quiescent current, and 1.5mm × 1.5mm UCSP packaging - making it the only viable option for space- and energy-constrained dual-channel analog front-ends in modern portable electronics.

FAQ
What is the minimum operating voltage for the MAX4292EBL-T?
The MAX4292EBL-T is fully specified and guaranteed to operate from a 1.8V single supply (or ±0.9V dual supply). While typical operation extends down to 1.5V, design margins should be based on the 1.8V minimum specification. This makes the MAX4292EBL-T compatible with end-of-life voltage of two-cell alkaline (1.8V) and NiMH (2.4V) batteries without regulation.
Does the MAX4292EBL-T support rail-to-rail input and output simultaneously?
Yes, the MAX4292EBL-T supports true rail-to-rail input common-mode range (0V to VCC) and rail-to-rail output swing (within 46mV of VEE and VCC into 2kΩ). This simultaneous capability enables full utilization of the supply voltage in low-headroom 1.8V systems - critical for maximizing ADC resolution and minimizing signal loss in portable instrumentation.
What package type is used for the MAX4292EBL-T?
The MAX4292EBL-T is packaged in an 8-bump, 1.5mm × 1.5mm ultra chip-scale package (UCSP™) with bottom-side solder bumps. This wafer-level package offers the smallest footprint among dual op-amps in its class and requires specific PCB layout practices including 0.5mm bump pitch, 0.25mm pad size, and multiple vias near ground pins.
Can the MAX4292EBL-T drive capacitive loads without oscillation?
The MAX4292EBL-T is unity-gain stable with capacitive loads up to 100pF. For loads exceeding 100pF - such as long PCB traces or large filter capacitors - an isolation resistor (e.g., 100Ω) must be placed in series with the output to maintain stability. Without this resistor, overshoot and ringing may occur, degrading signal integrity in precision applications.
How does the MAX4292EBL-T perform as a comparator?
Although optimized as an op amp, the MAX4292EBL-T can function as a rail-to-rail I/O comparator with propagation delay dependent on overdrive voltage (e.g., ~10µs at 100mV overdrive, VCC = 1.8V). However, supply current rises significantly (to ~1.5mA at VCC = 1.8V) in comparator mode, so sustained use in this configuration is not recommended for ultra-low-power designs.
