The MCP6491T-E/OT: The rail-to-rail output stage preserves dynamic range at low supply voltages, and the 1 pA input bias current suits high-impedance sensors such as photodiodes or pH probes.
Quiescent supply current is 530 µA per amplifier.
The MCP6491T-E/OT is supplied in a 5-pin SOT-23 package (SOT-23-5).
Yes, the output is rail-to-rail. The input common-mode range is not rail-to-rail, so high-side sensing at low supply voltages requires checking the input voltage limits.
The closest functional equivalent is the dual-channel MCP6492T-E/MNY, which shares the same 7.5 MHz GBWP, 6 V/µs slew rate, and supply range. For a single-channel alternative with higher bandwidth, consider the MCP6291T-E/MS (10 MHz, 7 V/µs).
