Product details

High-speed dual op-amp in a SOT-23-8 footprint

With a gain-bandwidth product of 175 MHz and rail-to-rail output, it is designed for high-speed signal conditioning where board space is tight — video distribution, ADC drivers, and gamma-buffer stages in TFT-LCD panels.

A 485 V/µs slew rate means the output can swing 10 V in roughly 20 ns. This is the spec that decides whether the amplifier can reproduce a fast pulse or a high-frequency sine wave without slew-induced distortion. For a 5 Vpp output at 50 MHz, the required slew rate is about 1.6 V/µs — this part has nearly 300× that margin, so it is not the slew rate that limits the signal chain; the 210 MHz small-signal bandwidth is the real ceiling. The dual-channel configuration (two circuits in one package) saves board area compared to two single op-amps, and each channel can deliver 70 mA output current.
