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
APPLICATIONS exceptional performance in monolithic form.
