Single general-purpose op-amp with rail-to-rail output — what the specs mean for your board
The Microchip MCP6L71T-E/MS is a single-channel general-purpose op-amp in an 8-MSOP package. It delivers a 2 MHz gain bandwidth product and a 0.9 V/µs slew rate, making it suitable for signal conditioning in industrial sensors, motor-drive feedback paths, and general-purpose analog processing where moderate bandwidth is enough. The quiescent current is 150 µA per channel — low enough for battery-operated equipment but not the lowest in the family; if every microamp matters, the MCP6L71T's sibling with a lower supply current is worth a look. Input bias current is 1 pA typical, which keeps offset drift negligible when interfacing with high-impedance sources like photodiodes or pH probes. Input offset voltage is 1 mV typical — adequate for 8- to 10-bit systems; for higher precision, a zero-drift amplifier would be a better fit. Output swings rail-to-rail, so it can drive an ADC input or a comparator without losing headroom at low supply voltages. The 0.9 V/µs slew rate means a full 5 V step settles in about 5.5 µs — fine for audio and slow control loops, but not for high-speed pulse amplification.
The -E suffix in the order code indicates the extended temperature range — confirm the full marking on the part if you receive reels, as the commercial-temperature variant (no -E) is a different code.
ROHS3 compliant per the supplier declaration. Because the lifecycle is clean, there is no forced migration to a successor.
