MAX4292ESA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4292ESA-T is a dual-channel micropower operational amplifier from the MAX4291/MAX4292/MAX4294 family. It operates on a single supply of 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V, consuming only 100µA per amplifier. Key electrical parameters include a 500kHz gain-bandwidth product, 120dB open-loop voltage gain, and a typical input offset voltage of ±200µV. The device features rail-to-rail inputs and outputs, with an output swing within 46mV of the rails under a 2kΩ load. It is housed in an 8-pin SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the manufacturer designation matches Analog Devices Inc./Maxim Integrated. Ensure the part number corresponds to the 8-pin SOIC package variant rather than other available packages like UCSP or µMAX. Cross-reference the datasheet revision to confirm electrical characteristics align with your design requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low-voltage operation down to 1.8V with high precision. The dual-channel configuration allows for space-constrained layouts while maintaining low power consumption. Consider the rail-to-rail I/O capabilities if signal swings must utilize the full supply range. Evaluate the 500kHz bandwidth against the required signal frequencies to ensure adequate performance without excessive power usage.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX429x family of micropower op amps, which includes single (MAX4291) and quad (MAX4294) variants. The family shares core specifications such as the 500kHz gain-bandwidth product and 100µA supply current. The MAX4292 specifically provides two amplifiers in an 8-pin format, offering a balance between channel count and physical footprint compared to the single-channel SC70 or quad-channel SO-14 options.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MAX4291EUA+ (single channel) and MAX4294ESA+ (quad channel), though pin counts differ. Other Maxim integrated Micropower Op Amps with similar rail-to-rail I/O and low supply current specifications may serve as functional alternatives if package compatibility is not strictly required.
