Product Summary

The OPA3691ID is a triple wideband, current-feedback operational amplifier with disable. The OPA3691ID sets a new level of performance for broadband, triple current-feedback op amps. Operating on a very low 5.1mA/ch supply current, the OPA3691 offers a slew rate and output power normally associated with a much higher supply current. A new output stage architecture delivers a high output current with minimal voltage head-room and crossover distortion. The applications of the OPA3691ID are (1)RGB amplifiers; (2)wideband ina; (3)broadband video buffers; (4)high-speed imaging channels; (5)portable instruments; (6)ADC buffers; (7)active filters; (8)cable drivers.

Parametrics

OPA3691ID absolute maximum ratings: (1)Power Supply: ±6.5VDC; (2)Differential Input Voltage: ±1.2V; (3)Input Voltage Range: ±VS; (4)Storage Temperature Range: ID, IDBQ: –40 to +125℃; (5)Lead Temperature (soldering, 10s): +300℃; (6)Junction Temperature (TJ): +175℃.

Features

OPA3691ID features: (1)flexible supply range: +5V to +12V Single-Supply; ±2.5V to ±6V Dual Supply; (2)unity-gain stable: 280MHz (G = 1); (3)high output current: 190mA; (4)output voltage swing: ±4.0V; (5)high slew rate: 2100V/μs; (6)low supply current: 5.1mA/ch; (7)low disabled current: 150μA/ch; (8)improved high-frequency pinout; (9)wideband +5v operation: 190MHz (G = +2).
