OPA4991IDYYR AI Analysis:
Datasheet, Specs, Alternatives & ECAD

It is intended for industrial analog signal paths such as multiplexed data acquisition, ADC driving, SAR ADC reference buffering, low-side or high-side current sensing, programmable logic controllers, and test equipment.

Confirm the output load and capacitive load stability, expected output current and thermal dissipation, and the input common-mode operating point. The input-stage crossover region is typically between V+ - 2 V and V+ - 1 V.

Key typical values are 4.5 MHz gain-bandwidth, 21 V/µs slew rate, ±125 µV input offset voltage, ±0.3 µV/°C offset drift, 560 µA quiescent current per amplifier, and ±75 mA short-circuit output current.
