OPA4991QDRQ1 TI Instrumentation, OP Amps, Buffer Amps

The OPA4991QDRQ1 is an automotive-grade (AEC-Q100) quad, high-voltage (40V), low-power operational amplifier from Texas Instruments featuring a gain bandwidth product of 4.5 MHz and a high slew rate of 21 V/µs. It operates over a wide supply range of 2.7V to 40V (or ±1.35V to ±20V) and draws a low quiescent current of 560 µA per amplifier. The device provides exceptional DC precision with low offset voltage of ±125 µV, low offset drift of ±0.3 µV/°C, low noise of 10.8 nV/√Hz at 1 kHz, and high CMRR of 130 dB. It features rail-to-rail input and output swing, high output current of ±75 mA, high capacitive load drive of 1 nF, and MUX-friendly/comparator inputs that allow the amplifier to operate with differential inputs up to the supply rail. Housed in a 14-pin SOIC (D) package, it operates over -40°C to 125°C. Applications include automotive sensor interfaces, body control modules, battery management systems, HEV/EV inverters, ADAS, and industrial controls requiring AEC-Q100 qualification.
