OPA454
SBOS391B – DECEMBER 2007 – REVISED MARCH 2016
9.1 Overview
The OPA454 is a low-cost operational amplifier (op amp) with high voltage (100 V) and a relatively high current
drive of 50 mA. This device is unity-gain stable and features a gain-bandwidth product of 2.5 MHz. The high-
voltage OPA454 offers excellent accuracy, wide output swing, and has no phase inversion problems that are
typically found in similar op amps. The device can be used in virtually any ±5-V to ±50-V op amp configuration,
and is especially useful for supply voltages greater than 36 V.
