What this quad op-amp delivers
The MAX4478AUD+T is a quad general-purpose op-amp from Analog Devices in a 14-TSSOP package. Input offset voltage is trimmed to 70 µV typical, and input bias current sits at 1 pA — negligible for most sensor interfaces. Supply current for all four amplifiers totals 2.5 mA, making it a practical choice for multi-channel signal conditioning where power budget matters.
Output drive and package
Each output can source or sink 48 mA. The 14-TSSOP body (4.40 mm width) is a compact footprint for dense PCBs.
