90 kHz GBWP — the bandwidth reality check
The MCP6424T-E/ST is a quad general-purpose op-amp from Microchip built for the low-power corner of the signal chain.
4.4 µA total supply — where the microamps get counted
The total supply current is 4.4 µA for all four amplifiers. Input bias current is 1 pA. Output drive is 22 mA per channel. Input offset is 1 mV typical.
14-TSSOP and temperature grade
The 14-TSSOP package is a surface-mount footprint with a 4.40 mm body width, common for space-constrained multi-channel boards. The 'E' in the order code marks the extended temperature grade, so a BOM line specifying this variant is locked into the wider range.
