This combination makes it suitable for high-speed signal conditioning, video distribution, and ADC driver stages where wide flat gain is needed before the loop rolls off. Slew rate is 1000 V/µs, which means the output can swing 5 V in 5 ns — fast enough to reproduce a 100 MHz square wave without visible rounding on a scope. The 20.2 mA supply current is the price you pay for that speed; it runs warm in the 8-SOIC package, so the board copper under the device helps pull heat away. Supply span is 8 V to 12 V single or split — a ±5 V rail pair fits right in the middle. Input bias current is 20 µA (bipolar input stage), and input offset voltage is 300 µV typical. For a DC-coupled photodiode front-end, that offset may need a trim or a downstream servo loop. ## Package, temperature grade, and lifecycle ROHS3 compliant per the lifecycle record.","metaTitle":"TI OPA843ID Voltage Feedback Op-Amp, 500 MHz, 8-SOIC","metaDescription":"Texas Instruments OPA843ID voltage feedback op-amp, 500 MHz -3dB bandwidth, 1000 V/µs slew rate, 8-SOIC package.
