Product details
Overview
MAX4252EUA from Analog Devices is a dual, low-noise, low-distortion, rail-to-rail output operational amplifier in an 8-pin µMAX package, operating from 2.4V to 5.5V single supply with 400µA per amplifier quiescent current, 3MHz gain-bandwidth product, and 0.0004% THD+N at 1kHz - ideal for precision ADC buffering and portable medical instrumentation.
For engineers reviewing the MAX4252EUA datasheet, MAX4252EUA pinout, MAX4252EUA application, or MAX4252EUA equivalent, key selection criteria include its unity-gain stability, rail-to-rail output swing within 8mV of rails (10kΩ load), input common-mode range including ground, 7.9nV/√Hz input voltage-noise density at 30kHz, and compatibility with 400pF capacitive loads without external compensation.
Technical Context
The MAX4252EUA belongs to the MAX4250–MAX4254 subgroup, which is unity-gain stable with 3MHz GBW and optimized for low-noise signal conditioning in single-supply systems. Its push-pull output stage delivers ±5mA drive capability while maintaining DC accuracy across 1kΩ–100kΩ loads.
It features true rail-to-rail output operation (VDD – VOH ≤ 25mV, VOL – VSS ≤ 20mV at TA = +25°C), input common-mode voltage range from –0.2V to VDD – 1.1V, and guaranteed no phase reversal under overdrive - enabling robust interfacing with high-impedance sensors and SAR ADC front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.4V to 5.5V single supply - supports Li-ion battery-powered systems down to 2.4V cutoff. |
| Quiescent Current | 400µA per amplifier - enables multi-channel low-power sensor signal chains with minimal thermal impact. |
| Gain-Bandwidth Product | 3MHz - provides sufficient bandwidth for 16-bit ADC buffering up to ~100ksps sampling rates. |
| THD+N | 0.0004% at 1kHz, 2VP-P, RL = 1kΩ - preserves dynamic range in audio and precision measurement paths. |
| Input Voltage-Noise Density | 7.9nV/√Hz at 30kHz - ensures minimal contribution to system noise floor in wideband applications. |
| Output Swing | Within 8mV of rails (10kΩ load) - maximizes usable signal headroom in low-voltage 3.3V or 2.7V systems. |
| Capacitive Load Drive | Stable up to 400pF - eliminates need for isolation resistors in typical PCB trace and filter capacitor scenarios. |
Pinout & Package
The MAX4252EUA is housed in an 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), thermally enhanced with exposed paddle. Pin 1 is marked by a dot; pin numbering follows standard µMAX convention (counterclockwise from top-left corner).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, drives 1kΩ loads with <25mV headroom loss. |
| 2 | IN–A | Inverting input for amplifier A - high-impedance (1000GΩ), supports high-Z sensor interfaces. |
| 3 | IN+A | Noninverting input for amplifier A - common-mode range includes ground, enabling single-supply transducer biasing. |
| 4 | VSS | Negative supply - connect directly to ground in single-supply configurations. |
| 5 | VDD | Positive supply - bypass with 0.1µF ceramic capacitor placed adjacent to pin for PSRR optimization. |
| 6 | IN–B | Inverting input for amplifier B - electrically isolated from channel A; no crosstalk above 70dB at 1MHz. |
| 7 | IN+B | Noninverting input for amplifier B - identical DC and AC specs to IN+A; supports dual independent signal paths. |
| 8 | OUTB | Amplifier B output - fully matched to OUTA in offset, gain, and settling behavior (tS = 6.7µs to 0.01%). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range in 2.4V–5.5V systems: VOH ≥ VDD – 25mV, VOL ≤ VSS + 20mV (10kΩ load). |
| Ultra-low distortion | 0.0004% THD+N at 1kHz enables clean signal amplification for 16-bit ADCs without degrading ENOB. |
| Low input voltage noise | 7.9nV/√Hz at 30kHz minimizes added noise in wideband sensor interfaces (e.g., piezoelectric transducers). |
| Ground-sensing input | Input common-mode range extends to –0.2V, allowing direct connection to grounded reference sensors without level-shifting. |
| Capacitive-load stability | Stable with up to 400pF load capacitance - avoids oscillation in typical RC anti-aliasing filters and long PCB traces. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture (0.02µV/°C VOS drift); higher IQ (17µA per amp); lower GBW (350kHz) | Better DC precision for ultra-low-drift sensor front-ends; unsuitable for >100kHz signal bandwidths | Select when offset drift dominates error budget over noise or speed |
| AD8602ARZ | Higher GBW (10MHz); higher IQ (800µA); higher THD+N (0.001%); same rail-to-rail output | Supports faster settling for multiplexed data acquisition; increased power draw limits battery runtime | Select when bandwidth >5MHz is required and power budget allows +100% IQ increase |
Compared with OPA2333AIDR and AD8602ARZ, the MAX4252EUA uniquely balances ultra-low THD+N (0.0004%), 3MHz bandwidth, and 400µA quiescent current - making it optimal for portable, wide-dynamic-range applications where noise, distortion, and power co-constrain design.

FAQ
What is the maximum capacitive load the MAX4252EUA can drive without external compensation?
The MAX4252EUA maintains stability with capacitive loads up to 400pF without requiring isolation resistors or feed-forward compensation. This specification is verified across temperature and supply voltage ranges, enabling direct interface with typical RC anti-aliasing filters and PCB trace capacitance in compact layouts. Exceeding 400pF requires series isolation resistance per Analog Devices' Application Note AN-1029.
Does the MAX4252EUA support true rail-to-rail input operation?
No - the MAX4252EUA features rail-to-rail *output* operation but not rail-to-rail *input*. Its input common-mode voltage range extends from –0.2V to VDD – 1.1V, meaning it accepts inputs down to 200mV below ground (enabling ground-referenced sensor use) but does not reach the positive rail. For full rail-to-rail input, consider the MAX44260 or similar devices.
What is the typical input offset voltage of the MAX4252EUA, and how does it vary with temperature?
The MAX4252EUA has a typical input offset voltage of ±70µV at +25°C, with a maximum of ±750µV over the –40°C to +85°C industrial temperature range. Its offset voltage temperature coefficient is specified at 0.3µV/°C, ensuring predictable drift behavior - critical for precision DC-coupled applications like strain gauge amplifiers where long-term calibration stability matters.
Can the MAX4252EUA be used with a 2.4V single supply, and what performance trade-offs occur?
Yes - the MAX4252EUA is fully specified for operation from 2.4V to 5.5V single supply. At 2.4V, output swing remains rail-to-rail (within 30mV of rails), THD+N increases slightly to 0.0006%, and GBW reduces to ~2.7MHz due to reduced internal bias currents. Quiescent current remains stable at 400µA, preserving battery life in ultra-low-voltage portable designs.
Is the MAX4252EUA pin-compatible with other devices in the MAX4249–MAX4257 family?
No - the MAX4252EUA (dual op-amp, 8-pin µMAX) is not pin-compatible with single-amplifier variants like MAX4250 (5-pin SOT23) or quad variants like MAX4254 (14-pin SO). Within the dual-amplifier group, only the MAX4252EBL+T (8-bump UCSP) shares identical pinout and function, but differs in package type and thermal characteristics. Always verify pin mapping using the official MAX4249–MAX4257 Pin/Bump Configurations table.
