OPA991QDBVRQ1 General Purpose Amplifier
The OPA991QDBVRQ1 is an automotive-grade, high-voltage, rail-to-rail input/output (RRIO), CMOS operational amplifier from Texas Instruments, housed in a compact SOT-23-5 package, designed for precision signal conditioning in demanding automotive and industrial environments. This device operates from a wide supply voltage range of 2.7 V to 40 V (±20 V), features a unity-gain stable bandwidth of 4.5 MHz, and a high slew rate of 21 V/µs, all while consuming a low quiescent current of 560 µA per channel and supporting the full automotive temperature range of -40°C to 125°C.
It delivers robust performance for harsh electrical environments, highlighted by its excellent electromagnetic interference (EMI) rejection, high capacitive load drive capability, and multiplexer-friendly input stage for simplified system design. Key specifications include a low input offset voltage of 895 µV (max), low input bias current of 10 pA, and a high common-mode rejection ratio (CMRR) of 130 dB, ensuring accuracy and stability. As a functional safety-capable device, it supports the development of systems requiring compliance with automotive safety standards.
