The OPA644 is a wideband precision current feedback operational amplifier featuring exceptionally high open loop transimpedance and high slew rate. The current feedback architecture allows for excellent large signal bandwidth, even at high gains. The high transimpedance allows this op amp to be used in applications requiring 16 bits or more of accuracy. This extra transimpedance at high bandwidths gives very low distortion and low differential gain and phase errors. The high slew rate and well-behaved pulse response allow for superior large signal amplification in a variety of RF, video and other signal processing applications. Fabricated on an advanced complementary bipolar process, the OPA644 offers exceptional performance in monolithic form.
