MAX4252EUA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4252EUA+T is a dual-channel, low-noise, low-distortion operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.4V to 5.5V and features rail-to-rail output capability. The device draws 400µA of quiescent current per amplifier and offers a gain-bandwidth product of 3MHz with unity-gain stability. Key electrical characteristics include an input offset voltage of 70µV, input bias current of 1pA, and total harmonic distortion plus noise of 0.0004% at 1kHz. It is housed in an 8-bump UCSP package.

• Medical Instrumentation
• ADC Buffers
• Digital Scales/Strain Gauges

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the 'E' designation corresponds to the extended temperature range of -40°C to +85°C. Ensure compatibility with the 8-bump UCSP footprint during PCB layout. Check for lead-free/RoHS compliance status as indicated by the '+' suffix in ordering information.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside high precision. The 3MHz bandwidth and unity-gain stability make it suitable for general-purpose buffering. Consider the UCSP package size for space-constrained designs. Verify that the required gain does not exceed unity, as higher-speed variants are needed for gains of 10V/V or greater.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4249–MAX4257 family of UCSP, single-supply, low-noise, low-distortion, rail-to-rail op amps. The MAX4252 specifically provides two amplifiers in a compact form factor. Unlike the decompensated members of the series, this model is optimized for unity-gain stability with a 3MHz gain-bandwidth product.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4252ESA+ and MAX4252EUA+ are electrically equivalent alternatives available in SO and µMAX packages respectively. These share the same pinout and specifications but differ in physical package dimensions.
