Texas Instruments OPA3693
The OPA3693 provides an easy to use, broadband, triple, fixed-gain buffer amplifier. The OPA3693 offers a slew rate (2500V/µs) and bandwidth (> 800MHz) normally associated with a much higher supply current. This combination of features makes the OPA3693 an ideal RGB line driver or single-supply undersampling analog-to-digital converter (ADC) input driver.| Part No. | OPA3693 |

DESCRIPTION
Depending on the external connections, the internal resistor network may be used to provide either a fixed gain of +2 video buffer or a gain of +1 or –1 voltage buffer. A new output stage architecture delivers high output current with a minimal headroom and crossover distortion. The OPA3693 13mA/channel supply current is precisely trimmed at +25°C. This trim, along with a low temperature drift, gives lower system power over temperature. System power can be further reduced using the optional disable control pin.
