DESCRIPTION
The OPA646 is a low power, wideband voltage feed-
back operational amplifier. It features a high
bandwidth of 650MHz as well as a 12-bit settling time
of only 15ns. Its low input bias current and wide
bandwidth allows it to be used for high speed integra-
tor and active filter designs. Its low distortion gives
exceptional performance for telecommunications,
medical imaging and video applications.
The OPA646 is internally compensated for unity-gain
stability. This amplifier has a fully symmetrical
differential input due to its “classical” operational
amplifier circuit architecture. Its unusual combination
of speed, accuracy and low power make it an ideal
choice for many portable, multichannel and other high
speed applications where power is at a premium.
