1.5 GHz CFA in an SOIC-8 — what it buys you
The Texas Instruments OPA694ID is a single-channel current-feedback operational amplifier in an 8-SOIC package. Its 1.5 GHz -3dB bandwidth and 1700 V/µs slew rate make it a fit for high-speed signal chains — think video distribution, ADC drivers, or wideband transimpedance amplifiers where settling time and pulse fidelity matter. The current-feedback topology means gain-bandwidth product isn't fixed; you trade closed-loop gain for bandwidth more predictably than with a voltage-feedback amp, which simplifies compensation in higher-gain stages. Supply range spans 7 V to 12.6 V single supply, or you can split rails. Quiescent draw is 5.8 mA. Temperature grade is -40°C to 85°C, covering most commercial and industrial environments. Input offset voltage is 500 µV typical, input bias current 5 µA — typical for a CFA with a bipolar input stage. Package is the standard 8-SOIC footprint, so it drops onto existing pads without a board spin.
Slew rate and bandwidth — the numbers that matter
The 1700 V/µs slew rate and 1.5 GHz -3dB bandwidth are the headline specs. For a current-feedback amp, the slew rate is largely independent of closed-loop gain.
