OPA991IDBVR TI Instrumentation, OP Amps, Buffer Amps

The OPA991 is a single high-voltage operational amplifier with 40 V capability, featuring rail-to-rail input and output. It operates from 2.7 V to 40 V single supply (or ±1.35 V to ±20 V dual) with low offset voltage, low noise, and excellent DC precision. The device includes shutdown capability, allowing the amplifier to enter low-power mode. Each amplifier consumes low quiescent current. Packaged in SOT-23-5, the OPA991 is designed for industrial and automotive applications requiring wide voltage range with shutdown. Selection is ideal for high-voltage, high-precision signal conditioning requiring power-saving shutdown mode. Applications include sensor signal conditioning in automotive systems, industrial controls, motor drives, power supply control loops, and battery management systems requiring rail-to-rail performance with shutdown for power optimization.
