Dual current-feedback amp with 1700 V/µs slew rate
The Texas Instruments OPA2658E is a dual-channel current-feedback operational amplifier in an 8-VSSOP package. Its defining characteristic is a 1700 V/µs slew rate, achieved while drawing only 10 mA per channel from a 9 V to 11 V supply span. The current-feedback topology means the gain-bandwidth product is not a fixed limit — the amp maintains high slew rate and bandwidth even as closed-loop gain increases, which is the key selection criterion for high-speed pulse, video distribution, or RF buffer stages where a voltage-feedback amp would trade bandwidth for gain.
Output drive and input offset — what the ratings mean
Each channel delivers 120 mA of output current. Input bias current is 30 µA. Operating temperature range is -40 to 85 °C.
The 8-VSSOP (0.118-inch body width) is a common small-outline footprint for dual op-amps. Surface-mount assembly only; the 3.00 mm width suits dense PCB layouts.
