MCP6V61T-E/OTVAO

Instrumentation, Op Amps, Buffer Amps Overview

The MCP6V61T-E/OTVAO is a single-channel zero-drift operational amplifier from Microchip Technology, housed in an SOT-23-5 surface-mount package. It features input offset voltage correction for high DC precision, with a maximum input offset voltage of ±8 µV and drift of ±15 nV/°C at 5.5V supply. The device operates on a single supply voltage ranging from 1.8V to 5.5V, drawing a typical quiescent current of 80 µA per amplifier. It offers a gain bandwidth product of 1 MHz, rail-to-rail input and output capabilities, and unity-gain stability.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'VAO' against official Microchip documentation to confirm automotive qualification status, as standard datasheets may not explicitly detail this variant's compliance. Ensure the ordering information matches the exact package type and temperature grade required for your design specifications before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high DC accuracy is critical without requiring external calibration due to its inherent zero-drift architecture. Consider the 1 MHz bandwidth and 80 µA current consumption balance for applications needing moderate speed with strict power constraints. Verify that the SOT-23-5 package fits your PCB layout constraints compared to other family members like the SC70 variant.
