Product details
Overview
The MAX4453EZA-T from Maxim Integrated is a dual, unity-gain stable, rail-to-rail output operational amplifier optimized for low-power, high-speed signal conditioning in portable systems. It delivers 200MHz -3dB bandwidth, 95V/µs slew rate, and consumes only 620µA per amplifier from a +2.7V to +5.25V single supply - enabling high-fidelity baseband amplification in cellular telephones and keyless entry receivers.
For engineers reviewing the MAX4453EZA-T datasheet, MAX4453EZA-T pinout, MAX4453EZA-T application, or MAX4453EZA-T equivalent, this page provides verified circuit role, validated Thin SOT23-8 package mapping, confirmed dual-amplifier topology with rail-to-rail output swing, and two rigorously cross-referenced alternative op amps for low-voltage, wide-bandwidth design reuse.
Technical Context
The MAX4453EZA-T implements a voltage-feedback architecture with internal unity-gain compensation, ensuring stability without external compensation components. Its bipolar process enables fast large-signal response (20ns rise/fall time) and low distortion (–79dBc SFDR at 3V, 1MHz), critical for ADC input buffering and active filter stages.
Designed for single-supply operation, it features ground-sensing inputs (common-mode range extends to VEE – 0.1V) and rail-to-rail outputs (within 180mV of rails at 1kΩ load), maximizing dynamic range in 3V systems. Output stage feedback ensures low open-loop output impedance (<0.8Ω at 1MHz), reducing gain sensitivity to load variations.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4453ESA | Same die, SO-8 package (4.9mm × 6.0mm); higher thermal mass but larger footprint | Preferred where board space permits and higher power dissipation margin is needed | Select MAX4453ESA for industrial designs requiring SO-8 reflow compatibility and enhanced thermal derating |

FAQ
What is the operating supply voltage range for the MAX4453EZA-T?
The MAX4453EZA-T operates from a single +2.7V to +5.25V supply. This range accommodates standard Li-ion battery voltages (3.0V–4.2V) and regulated 3.3V or 5V system rails. The device maintains full AC performance across this range, with supply current varying from 530µA at 3V to 620µA at 5V per amplifier.
Is the MAX4453EZA-T unity-gain stable?
Yes, the MAX4453EZA-T is internally compensated for unity-gain stability. It achieves stable operation with closed-loop gains ≥1V/V without external compensation components. This makes it suitable for voltage follower, active filter, and ADC input buffer configurations where minimal external parts are required.
What package type does the MAX4453EZA-T use?
The MAX4453EZA-T uses an 8-pin Thin SOT23 package (JEDEC MO-178), measuring 3.00mm × 2.60mm × 0.90mm with 0.65mm lead pitch. This ultra-compact outline is optimized for high-density portable PCB layouts while maintaining thermal performance up to +85°C ambient.
Does the MAX4453EZA-T support rail-to-rail output swing?
Yes, the MAX4453EZA-T delivers rail-to-rail output swing - typically within 180mV of VCC and 75mV of VEE at 1kΩ load. This maximizes dynamic range in low-voltage systems, allowing full utilization of 3V ADC input ranges and improving signal-to-noise ratio in battery-powered applications.
