Product details
Overview
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 on a +2.7V to +5.25V single supply - enabling use in battery-powered cellular telephones and keyless entry baseband circuits.
For engineers reviewing the MAX4453EZA+T datasheet, MAX4453EZA+T pinout, MAX4453EZA+T application, or MAX4453EZA+T equivalent, this page provides verified electrical specifications, Thin SOT23-8 package mapping, dual-channel op amp functional context, and validated alternative options for low-voltage wideband analog front-end design.
Technical Context
The MAX4453EZA+T implements a voltage-feedback architecture with internal unity-gain compensation, supporting stable operation at AVCL = +1V/V across its full bandwidth. Its bipolar process enables fast large-signal response (20ns rise/fall) and low distortion (–83dBc SFDR at 5V, 1MHz), critical for ADC input buffering and active filter stages.
Rail-to-rail output swing (within 180mV of rails at 1kΩ load) and ground-sensing input (common-mode range from VEE – 0.1V to VCC – 1.5V) maximize dynamic range in single-supply systems. Output stage feedback ensures low open-loop output impedance (<0.8Ω at 1MHz), reducing gain sensitivity to load variations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, unity-gain stable, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4453ESA | Same die, SO-8 package (4.9mm × 6.0mm) - 3.5× larger footprint, higher thermal mass | Preferred for prototyping, manual soldering, or thermally demanding industrial environments | Select MAX4453ESA when board space permits and thermal derating above 70°C is required |
| AD8052ARZ | Higher supply current (6.5mA per amp), wider bandwidth (110MHz), no rail-to-rail output (1.2V headroom) | Used in high-speed test equipment where power efficiency is secondary to settling time | Choose AD8052ARZ only if >100MHz bandwidth is needed and 3.3V rail-to-rail swing is not required |
Compared with MAX4453ESA and AD8052ARZ, the MAX4453EZA+T uniquely balances ultra-low power (620µA), full rail-to-rail output, and 200MHz bandwidth in a 2.9mm² Thin SOT23 package - making it optimal for miniaturized battery-operated RF and sensor interfaces where size and energy budget are constrained.

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 is guaranteed by PSRR testing and supports direct interfacing with 3.3V and 5V logic systems, as well as Li-ion and alkaline battery sources without regulation. Operation outside this range may cause permanent damage.
Is the MAX4453EZA+T unity-gain stable?
Yes, the MAX4453EZA+T is internally compensated for unity-gain stability (AVCL = +1V/V). It achieves 200MHz -3dB bandwidth and 95V/µs slew rate in this configuration without external compensation components, simplifying design for buffer and gain applications.
What is the maximum capacitive load the MAX4453EZA+T can drive without oscillation?
The MAX4453EZA+T is characterized for stable operation with ≥22pF capacitive loads. Driving larger loads (e.g., ADC input capacitance plus PCB trace capacitance) may reduce phase margin; an isolation resistor (RISO) is recommended per Figure 1 in the datasheet to restore stability.
Does the MAX4453EZA+T feature rail-to-rail input capability?
No - the MAX4453EZA+T features rail-to-rail *output* but has a ground-sensing *input* with common-mode range from (VEE − 0.1V) to (VCC − 1.5V). At VCC = 3.3V, inputs operate from –0.1V to +1.8V, allowing direct connection to sensors referenced to ground.
What is the typical input offset voltage matching between the two amplifiers in the MAX4453EZA+T?
The MAX4453EZA+T specifies ±1mV maximum input offset voltage matching between its two amplifiers (INA+/INA− vs INB+/INB−). This tight matching enables precise differential signal conditioning and reduces common-mode error in instrumentation-grade dual-channel configurations.
