OPA4991IPWR TI Instrumentation, OP Amps, Buffer Amps

The OPA4991 is a quad 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) and offers a 4.5-MHz gain-bandwidth product, 20-V/μs slew rate, and low offset voltage of 0.5 mV typical. Input bias current is 10 pA, with low noise of 9 nV/√Hz. Each amplifier consumes 0.85 mA supply current. The device is unity-gain stable and includes shutdown capability in some variants. Packaged in a 14-pin TSSOP, the OPA4991 is ideal for high-voltage, high-precision signal conditioning requiring four op-amps. Applications include sensor signal amplification for industrial controls, automotive systems, motor drives, and power supply control loops.
