These two numbers together define the large-signal and small-signal bandwidth: the GBWP sets the closed-loop bandwidth at a given gain (e.g., 270 MHz at a gain of 10), while the slew rate determines how fast the output can swing under a large step input — 1400 V/µs means it slews 1.4 V in 1 ns, critical for driving ADC inputs or pulse-recovery stages where the signal edge must not be the limiting factor. The -3 dB bandwidth of 765 MHz confirms the small-signal flatness extends well into the UHF band. For a photodiode transimpedance amplifier or a high-speed data acquisition front-end, this bandwidth supports settling times in the sub-nanosecond range, provided the feedback network and layout do not add parasitic poles. ## JFET input stage — bias current and noise floor for high-impedance sources The JFET input stage gives a typical input bias current of 25 pA at 25 °C. This is the key spec for a sensor front-end: a 10 MΩ source impedance sees only 250 µV of offset from bias current, negligible compared to the 1.25 mV typical input offset voltage. The bias current doubles roughly every 10 °C, so at 85 °C it sits near 400 pA — still acceptable for most high-impedance paths, but worth derating for a 100 MΩ piezoelectric sensor. Supply current is 26.5 mA typical, drawn from a single supply span of 6 V to 13 V. The 110 mA output current per channel gives enough drive to swing into a 50 Ω load or a 100 Ω feedback network without significant gain compression. ## Package and thermal — 8-SON with exposed pad Housed in an 8-WFDFN exposed-pad package (3×3 mm body, 8-SON), the OPA818IDRGT requires a thermal-land pattern on the PCB. Tape & Reel (TR) and Cut Tape (CT) options are available for production and prototyping quantities respectively. ## Lifecycle and supply-chain posture For BOM planning, the active status means no imminent obsolescence risk.","metaTitle":"TI OPA818IDRGT JFET Op-Amp, 2.7 GHz GBWP, 1400V/µs","metaDescription":"Active JFET op-amp, 2.7 GHz GBWP, 1400 V/µs slew rate, 765 MHz -3dB bandwidth. 8-SON package, -40 to 125°C.

This means the output can change by 1.4 V in one nanosecond. For a 2 V peak-to-peak output swing, the full-power bandwidth is roughly 110 MHz — above that, the output slew-rate limits the undistorted swing. It is suited for driving high-speed ADCs, pulse amplifiers, and video distribution where fast edge rates are required."},{"question":"Is the OPA818IDRGT RoHS compliant?","answer":"Yes, the OPA818IDRGT is ROHS3 Compliant per Texas Instruments' lifecycle designation."},{"question":"What package does the OPA818IDRGT come in?","answer":"The OPA818IDRGT is supplied in an 8-WFDFN exposed-pad package, also designated as 8-SON with a 3×3 mm body.
