MAX495CPA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX495CPA+ is a single-channel, micropower operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features rail-to-rail input and output capabilities, allowing operation from a single supply of +2.7V to +6V or split supplies of ±1.35V to ±3V. Key electrical parameters include a maximum quiescent current of 150µA per amplifier, a gain-bandwidth product of 500kHz, and an input offset voltage of 200µV. The device operates within a temperature range of 0°C to +70°C and is housed in an 8-pin PDIP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component status before procurement as the MAX495 was manufactured using a process that is no longer available. The datasheet explicitly states this part is Not Recommended for New Designs. Confirm availability through authorized distributors or second-source manufacturers, as original production may be discontinued. Ensure the ordering suffix matches the required package and temperature grade specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX495CPA+ for designs requiring low-voltage, single-supply operation with precision DC accuracy. Consider its rail-to-rail performance for maximizing dynamic range in low-voltage systems. Evaluate the 150µA supply current against power constraints. Note that external offset nulling is supported via NULL pins, which is unique to the single-channel version compared to dual or quad variants.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX495 is part of the MAX492/MAX494/MAX495 family of Single/Dual/Quad, Micropower, Single-Supply Rail-to-Rail Op Amps. While the MAX492 (dual) and MAX494 (quad) share similar electrical characteristics, the MAX495 provides a single amplifier channel. All variants utilize industry-standard pin configurations for DIP and SO packages, facilitating drop-in replacements in existing designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

As the MAX495 is not recommended for new designs due to manufacturing process discontinuation, consult Maxim technical support for replacement options. Industry second-sources may be available. Verify functional compatibility if substituting with other single-channel rail-to-rail op amps.
