OPA541AM

Instrumentation, Op Amps, Buffer Amps Overview

The OPA541AM is a high-power monolithic operational amplifier manufactured by Texas Instruments, utilizing BiFET technology. It operates within a supply voltage range of 20 V to 70 V single or ±10 V to ±35 V dual. Key electrical parameters include a gain-bandwidth product of 2 MHz, a slew rate of 10 V/µs, and an input bias current of 50 pA. The device delivers a continuous output current of 5 A with peak capability up to 10 A. It features a common-mode rejection ratio of 113 dB and an input offset voltage of 10 mV. The component is housed in a TO-3-8 package designed for through-hole mounting.
