For a pulse amplifier or video line driver, that slew rate translates directly to the maximum undistorted output swing at a given frequency. The -3 dB bandwidth is 280 MHz, but unlike a voltage-feedback op-amp, the bandwidth of this current-feedback design is set by the value of the feedback resistor, not the closed-loop gain. You trade bandwidth for stability by choosing that resistor. ## Supply current, temperature range, and package fit Supply current is 5.1 mA, which is modest for a 2100V/µs amplifier. That combination makes it a candidate for multi-channel boards where each channel needs high slew rate but the total power budget is tight. The operating temperature range is -40°C to +85°C, covering industrial environments. An amplifier that lives on a factory-floor sensor interface or an outdoor communication node needs that range; a 0°C to 70°C part would not survive the same duty. It comes in an 8-SOIC package (0.154\" body width, 3.90 mm). That is a standard footprint shared by hundreds of op-amps, so the PCB layout is not locked to this one part. If you ever need to swap in a different CFA, the pads are the same. ## Sourcing and compliance for the BOM line The OPA691ID is ROHS3 Compliant, meeting the latest EU restriction of hazardous substances directive. No separate exemption paperwork is needed for shipping into regulated markets. It is supplied in tube packaging. For high-volume pick-and-place, you may want to confirm tube vs tape-and-reel availability with your distributor at quote time, as the tube quantity affects feeder setup. As an active Texas Instruments part, the OPA691ID is sourced to order through authorized and independent distribution. Lead time and current pricing are confirmed at RFQ against your BOM quantity.","metaTitle":"Texas Instruments OPA691ID Current Feedback Op-Amp, 2100V/µs","metaDescription":"OPA691ID from Texas Instruments, active production.
