Its headline rating is a 2100 V/µs slew rate combined with 280 MHz gain-bandwidth and -3 dB bandwidth. Each of the three channels delivers 190 mA of output current, enough to drive 50-ohm or 75-ohm terminated cables directly without a separate line driver. ## Package and supply — what to plan for on the board Supply voltage is 5 V minimum, 12 V maximum. At 15.3 mA supply current per amplifier, the triple draws about 46 mA total — budget that on the rail.","metaTitle":"TI OPA3691IDBQT Current Feedback Op Amp, 2100V/µs Slew Rate","metaDescription":"Texas Instruments OPA3691IDBQT triple current-feedback op amp: 280 MHz bandwidth, 2100 V/µs slew rate, 190 mA output.
