The zero-drift topology also suppresses 1/f noise, so the noise floor stays flat down to DC — useful for weigh scales or strain-gauge readouts that integrate over seconds. Rail-to-rail output swing lets it drive an ADC input full-scale on the same supply. The part can sit on an engine bay PCB, an outdoor solar inverter control board, or a downhole sensor module that sees the full thermal cycle. ## Slew rate and bandwidth — what they mean for signal fidelity For faster signals, the MCP6V91 family (10 MHz, 9.5 V/µs) is a step up in speed while keeping the zero-drift topology. ## Single-supply operation — yes, and here is the catch The input common-mode range extends from the negative rail to within about 1 V of the positive rail — it is not a true rail-to-rail input, so for a 3.3 V single-supply circuit, the input must stay below roughly 2.3 V to maintain linearity. The output, however, swings rail-to-rail, so it can drive an ADC input full-scale. This combination is typical for zero-drift amplifiers and works well for ground-referenced signals like shunt currents or grounded thermocouples.","metaTitle":"Microchip MCP6V28-E/SN Zero-Drift Op-Amp, 2 MHz, 8-SOIC","metaDescription":"MCP6V28-E/SN zero-drift op-amp: 2 µV offset, 2 MHz GBWP, 1 V/µs slew, 2.3-5.5 V supply, -40 to 125°C, 8-SOIC.
