Current-feedback amp delivers high bandwidth

Due to its current-feedback architecture, the OPA2695 dual-channel, high-speed current feedback amplifier can deliver a bandwidth of 850 MHz at a gain of 2 V/V and a fast slew rate of 2900 V/µs to process high-speed signals. The device provides second-order harmonics (HD2) of 94 dBc and third-order harmonics (HD3) of 93.5 dBc at 10 MHz for differential signals, and HD2 of better than 90 dBc up to 55 MHz at a large gain of 10 V/V.

At 5 V, the device delivers ±90-mA output current with a 3.4 Vpp. To further reduce power consumption, a power down option is also available, which reduces the quiescent current consumption to 80 µA. Housed in SO-8 and QFN-16 packages (with an optimized differential pinout), the OPA2695 operates from a single 3.5 to 12-V supply or a dual ±1.75 to ±6-V supply. ($2.10 ea/1,000 — available now.)
