Description
General part information
OPA690 Series
The OPA690 device represents a major step forward in unity-gain stable, voltage-feedback op amps. A new input architecture provides slew rate and full-power bandwidth previously found only in wide-band, current-feedback op amps. A new output stage architecture delivers 215mA of current with a minimal headroom requirement. These capabilities combine to give exceptional slew rate of 1900V/µs into a 100Ω load. The ultra-fast settling time of 13ns makes the OPA690 an excellent choice for fast sampling systems such as high-speed ADC drivers, high-speed imaging systems, and current DAC transimpedance amplifier.
The low quiescent current of 6.1mA makes the OPA690 an excellent choice in portable or battery-powered application. System power can be reduced further using the optional disable control pin (DIS). Leaving DIS open, or holding DIS high, operates the OPA690 normally. If DIS is pulled low, the OPA690 supply current drops to less than 100µA while the output goes to a high-impedance state.
