MAX495ESA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX495ESA+T is a single operational amplifier from the MAX492/MAX494/MAX495 family, manufactured by Analog Devices Inc./Maxim Integrated. It features rail-to-rail input and output operation with a supply voltage range of 2.7V to 6V. The device draws a maximum quiescent current of 150µA per amplifier while maintaining a gain-bandwidth product of 500kHz. Key electrical specifications include a typical input offset voltage of 200µV, an input noise voltage density of 25nV/√Hz, and high open-loop gain of 108dB. It operates within temperature ranges of -40°C to +85°C for the E-grade variant.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure the ordering suffix matches the required package type and temperature grade. Validate that the source provides official documentation for the specific revision level.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring precision amplification with minimal power consumption. The rail-to-rail characteristics make it suitable for single-supply systems where signal integrity near the supply rails is critical. Consider the offset null pins if precise DC accuracy is required without external trimming circuitry complexity.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX495 is part of a family including the dual MAX492 and quad MAX494 variants. These devices share identical electrical characteristics but differ in channel count. The MAX495 is specifically designed as a single-channel solution, offering a compact footprint in SOIC-8 and µMAX packages. It serves as a micropower alternative to standard CMOS op amps in portable electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet explicitly states the MAX495 is Not Recommended for New Designs due to the unavailability of the manufacturing process. Users should consult Maxim Integrated for replacement options or industry second-sources. Existing designs may continue using this part, but new implementations should consider modern equivalents.
