OPA2891DR TI Instrumentation, OP Amps, Buffer Amps
The OPA2891DR is a dual ultra-low voltage noise, high-speed voltage feedback amplifier from Texas Instruments featuring 0.95 nV/√Hz voltage noise and a unity gain bandwidth of 180 MHz. It operates over a wide supply range of ±4.5V to ±18V and provides a high slew rate of 105 V/µs and 70 ns settling time (0.1%). The device features very low total harmonic distortion of -100 dBc at f = 1 MHz and -137 dBc THD+N (80 kHz BW), 200 mA output current drive, low input offset voltage of 0.2 mV typical, and draws only 7.5 mA supply current per channel. Housed in an 8-pin SOIC (D) package, it operates over -40°C to 85°C. Applications include buffering analog-to-digital converters (ADCs), communications infrastructure, imaging systems, and high-speed active filters.
