Precision zero-drift op-amp for industrial sensing
The Microchip MCP6V86UT-E/LTY is a single-channel zero-drift (chopper) operational amplifier from the Zero-Drift series, designed to deliver low offset and drift over temperature without the need for external trimming. The rail-to-rail output stage maximizes dynamic range on low-voltage supplies, and the 2 pA typical input bias current preserves signal integrity when interfacing with high-impedance sources like photodiodes or pH probes.
Key specs for the BOM decision
The 2 pA bias current means the voltage error from a 10 kΩ source is just 20 nV, negligible even in microvolt-level measurements. Output drive capability of 40 mA per channel is enough to swing a 2 V signal into a 50 Ω load or drive the reference input of a successive-approximation ADC directly.
No exposed thermal pad, so thermal dissipation relies on the leadframe and copper pours on the PCB.
ROHS3 compliant per the compliance record, which covers the current RoHS exemption list without requiring a separate lead-free qualification step.
