Product details
Overview
MAX4352EXK+T from Maxim Integrated is a single-channel, high-speed, rail-to-rail output operational amplifier optimized for minimum closed-loop gain of +5V/V, delivering 80MHz -3dB bandwidth, 240V/µs slew rate, and ultra-low 620µA supply current per amplifier. It operates from a +2.7V to +5.25V single supply and is used in battery-powered RF front-ends and keyless entry receiver signal chains.
For engineers reviewing the MAX4352EXK+T datasheet, MAX4352EXK+T pinout, MAX4352EXK+T application, or MAX4352EXK+T equivalent, this page provides verified electrical specs, SC70-5 package details, real-world use cases in portable communications, and validated alternative options for low-power, high-bandwidth op amp selection.
Technical Context
The MAX4352EXK+T employs a voltage-feedback architecture with internal compensation for stable operation at closed-loop gains ≥ +5V/V. Its bipolar process enables fast large-signal response (8ns rise/fall time) and low distortion (–74dBc SFDR at 1MHz), while maintaining rail-to-rail output swing within 180mV of either supply rail under 1kΩ load.
Designed for AC-critical applications, it features low input capacitance (2pF), high capacitive load drive capability (22pF), and demand-driven output biasing that minimizes open-loop output impedance - critical for driving ADC input networks and active filter stages without stability degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4452EXK+T | Unity-gain stable, 200MHz BW, 95V/µs SR, same SC70-5 package | Better for unity-gain buffers and wideband AC coupling; unsuitable for +5V/V fixed-gain stages without external compensation | Select when circuit requires stable operation at G = 1 and higher bandwidth is prioritized over slew rate |
| ADA4891-1ARJZ-R7 | Unity-gain stable, 225MHz BW, 170V/µs SR, 1.2mA IQ, SOT23-5 | Higher power consumption; superior PSRR (80dB) but lower rail-to-rail output drive capability | Prefer when system-level power budget allows >1mA per channel and supply rejection is critical |
Compared with MAX4352EXK+T, MAX4452EXK+T trades slew rate and gain stability for wider bandwidth, while ADA4891-1ARJZ-R7 offers higher PSRR at the cost of 94% higher quiescent current - making MAX4352EXK+T optimal for battery-critical, fixed-gain, high-slew applications.

FAQ
What is the minimum stable closed-loop gain for MAX4352EXK+T?
The MAX4352EXK+T is internally compensated for stable operation at a minimum closed-loop gain of +5V/V. Attempting unity-gain or gains below +5V/V may cause peaking or oscillation. For G = 1 applications, use the pin-compatible MAX4452EXK+T instead. This gain constraint is hard-coded in the device's compensation network and cannot be overridden externally.
Does MAX4352EXK+T support rail-to-rail input operation?
No - the MAX4352EXK+T features rail-to-rail *output* but not rail-to-rail *input*. Its input common-mode voltage range is specified from VEE – 0.1V to VCC – 1.5V. With a 3.3V supply, this means inputs must stay between –0.1V and +1.8V; signals near VCC will saturate the input stage. Ground-sensing capability enables true 0V input, but VCC-referenced signals require level-shifting.
Can MAX4352EXK+T drive a 100Ω load directly?
No - the MAX4352EXK+T is characterized for RL = 1kΩ. Driving 100Ω loads exceeds its specified output current capability (15mA sourcing / 22mA sinking). Under 100Ω, output swing collapses significantly (to ~1.2Vpp on 3.3V supply), and distortion rises sharply. For low-Z loads, add an external buffer or select a current-feedback amplifier like the MAX4382.
What decoupling capacitor is recommended for MAX4352EXK+T?
A 0.1µF X7R ceramic capacitor placed ≤2mm from the VCC pin to ground is mandatory for stable operation. This value is validated in Maxim's layout guidelines and suppresses high-frequency supply noise that degrades PSRR and introduces intermodulation distortion. A second 1µF tantalum or ceramic capacitor may be added in parallel for low-frequency ripple suppression in noisy environments.
Is MAX4352EXK+T compatible with lead-free reflow profiles?
Yes - the MAX4352EXK+T SC70 package is rated for standard lead-free reflow (JEDEC J-STD-020 Rev E), with peak temperature tolerance up to +260°C for 30 seconds. The device is RoHS-compliant and halogen-free. Moisture sensitivity level is MSL1 - no baking required prior to assembly.
