Product details

50 MHz GBWP, 30 V/µs slew — signal-chain fit

The 6 mA supply current per channel is a reasonable trade-off for the speed; if your design runs on a coin cell, the 100 mA output drive capability means you can directly drive a small relay or LED without a buffer transistor.

The extended temperature grade means the offset drift and gain-bandwidth stability are characterised across the full range — not just at 25°C. If your board sees thermal cycling, the SOT-23-5 package's low thermal mass tracks junction temperature closely; keep the copper pour under the part generous to spread heat.

The SOT-23-5 footprint is shared across many Microchip op amps, so a pin-compatible swap (e.g., MCP6291) is possible if supply tightens, though the GBWP and slew rate differ.
