в—Џ SOT23-6 AVAILABLE The OPA693 provides an easy to use, broadband, fixed gain
buffer amplifier. 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 В±1 voltage buffer.
Operating on a low 13mA supply current, the OPA693 offers
a slew rate (2500V/Вµs) and bandwidth (> 700MHz) normally
associated with a much higher supply current. A new output
stage architecture delivers high output current with a minimal
headroom and crossover distortion. This gives exceptional
single-supply operation. Using a single +5V supply, the …
