Product details
Overview
MAX4252ESA from Analog Devices is a dual, low-noise, low-distortion, rail-to-rail output operational amplifier optimized for single-supply operation from 2.4V to 5.5V. It delivers 400µA quiescent current per amplifier, 0.0002% THD+N at 1kHz, 7.9nV/√Hz input voltage-noise density, and 3MHz gain-bandwidth product while maintaining unity-gain stability - ideal for precision ADC buffering and portable instrumentation.
For engineers reviewing the MAX4252ESA datasheet, MAX4252ESA pinout, MAX4252ESA application, or MAX4252ESA equivalent, key selection criteria include its rail-to-rail output swing within 8mV of rails (10kΩ load), input common-mode range extending to ground, 400pF capacitive-load drive capability, and compatibility with low-voltage, battery-powered signal chains requiring high DC accuracy and low noise.
Technical Context
The MAX4252ESA belongs to the MAX4249–MAX4257 family of single-supply op amps featuring a push-pull output stage enabling true rail-to-rail swing and ±5mA output drive. Its input stage supports common-mode voltages down to VSS (ground) and up to VDD − 1.1V, with guaranteed no phase reversal under overdrive.
It is unity-gain stable (GBW = 3MHz), distinct from decompensated variants like MAX4249/MAX4255 (22MHz, AV ≥ 10V/V). The device lacks shutdown functionality - confirmed by Pin Description table and Ordering Information, which list shutdown only for MAX4249/MAX4251/MAX4253/MAX4256.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 3MHz - enables stable unity-gain operation with sufficient bandwidth for audio and sensor signal conditioning up to ~100kHz closed-loop. |
| Input Voltage-Noise Density | 7.9nV/√Hz at 30kHz - ensures minimal added noise in precision amplification of low-level signals such as strain gauges or medical transducers. |
| THD+N | 0.0002% at 1kHz, 1kΩ load - preserves signal fidelity in high-resolution data acquisition systems (e.g., 16-bit ADC front-ends). |
| Output Swing | Within 8mV of rails (10kΩ load) - maximizes dynamic range in low-voltage systems (e.g., 3V or 3.3V supply rails). |
| Quiescent Current | 400µA per amplifier - supports extended battery life in portable equipment without sacrificing DC precision. |
| Input Offset Voltage | ±0.07mV (typ) - enables accurate DC-coupled amplification with <100µV error, critical for digital scale and medical instrumentation. |
| Capacitive Load Drive | 400pF - allows direct interface to ADC input capacitors or long PCB traces without external isolation resistors. |
Pinout & Package
MAX4252ESA is housed in an 8-pin SO (Small Outline) package with exposed pad (package code S8+1 per Analog Devices outline 21-0041), rated for -40°C to +85°C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, drives loads ≥1kΩ with DC accuracy preserved. |
| 2 | IN−A | Inverting input for Amplifier A - high-impedance (1000GΩ), supports ground-sensing configurations. |
| 3 | IN+A | Noninverting input for Amplifier A - common-mode range includes ground, enabling single-supply sensor interfacing. |
| 4 | VSS | Negative supply - connect to ground in single-supply mode; defines reference for input/output voltage ranges. |
| 5 | VDD | Positive supply - accepts 2.4V to 5.5V; requires local 0.1µF ceramic bypass capacitor. |
| 6 | IN−B | Inverting input for Amplifier B - electrically isolated from Amplifier A; supports dual-channel independent signal paths. |
| 7 | IN+B | Noninverting input for Amplifier B - identical DC and AC specs to IN+A; enables matched dual-channel designs. |
| 8 | OUTB | Amplifier B output - fully independent, rail-to-rail, with same drive strength and noise performance as OUTA. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Swings to within 8mV of VDD and VSS with 10kΩ load - preserves full ADC input range in 3V systems. |
| Ground-sensing input | Input common-mode range includes VSS (0V) - eliminates need for level-shifting when amplifying unipolar sensor outputs. |
| Low THD+N | 0.0002% at 1kHz - meets fidelity requirements for 16-bit analog-to-digital conversion without post-processing correction. |
| High DC precision | 70µV max input offset voltage and 116dB large-signal voltage gain - ensures accurate low-frequency amplification in weighing and medical applications. |
| Capacitive-load stability | Stable with up to 400pF load - simplifies design for ADC driver stages without compensation networks or isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, rail-to-rail, low-noise 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 noise (5.5nV/√Hz); GBW = 350kHz | Better DC stability over temperature; lower bandwidth limits use in >100kHz signal chains | Select when ultra-low offset drift dominates over speed and power; not suitable for 3MHz signal paths. |
| AD8602ARZ | Higher GBW (10MHz); higher IQ (800µA); higher THD+N (0.001%); same SO-8 package | Supports faster settling and higher closed-loop gains but consumes >2× current and adds distortion in precision ADC buffers | Choose when bandwidth >3MHz is required and power budget allows; verify THD+N impact on system ENOB. |
Compared with OPA2333AIDR and AD8602ARZ, the MAX4252ESA uniquely balances 3MHz bandwidth, 400µA power, sub-0.0003% THD+N, and rail-to-rail output in an industry-standard SO-8 footprint - making it optimal for cost-sensitive, battery-powered precision measurement where speed, noise, and power must coexist.

FAQ
What is the operating temperature range for MAX4252ESA?
The MAX252ESA is specified for operation from -40°C to +85°C, as confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet. This industrial temperature grade makes it suitable for deployment in portable test equipment, environmental sensors, and field-deployable medical devices without thermal derating concerns.
Does MAX4252ESA include a shutdown feature?
No, MAX4252ESA does not include a shutdown feature. The datasheet explicitly states that shutdown is available only on MAX4249/MAX4251/MAX4253/MAX4256 (Note 2), and the Pin Description table shows "N.C." for SHDN on MAX4252. Therefore, MAX4252ESA operates continuously when powered and draws 400µA per amplifier at all times.
What is the maximum capacitive load MAX4252ESA can drive without oscillation?
MAX4252ESA is stable driving capacitive loads up to 400pF, as verified in the Electrical Characteristics table under "Capacitive-Load Stability" and confirmed in Applications Information. Exceeding this value requires an isolation resistor (e.g., 150Ω for 1000pF) between output and load to maintain phase margin and prevent peaking.
Can MAX4252ESA operate from a 2.4V single supply?
Yes, MAX4252ESA supports single-supply operation from 2.4V to 5.5V, as stated in the General Description and Electrical Characteristics (Supply Voltage Range). At 2.4V, it maintains rail-to-rail output swing, ground-sensing input, and 400µA quiescent current - enabling use in coin-cell or Li-ion single-cell powered systems.
Is MAX4252ESA unity-gain stable?
Yes, MAX4252ESA is unity-gain stable with a 3MHz gain-bandwidth product, as clearly designated in the Selector Guide and Detailed Description. This distinguishes it from decompensated variants (e.g., MAX4249) and ensures stable operation in voltage-follower, active filter, and transimpedance configurations without external compensation.
