The OPA4650 is a quad, low power, wideband voltage feedback operational amplifier. It features a high bandwidth of 360MHz as well as a 12-bit settling time of only 20ns. The low input bias current allows its use in high-speed integrator applications, while the wide bandwidth and true differential input stage make it suitable for use in a variety of active filter applications. Its low distortion gives exceptional performance for telecommunications, medical imaging and video applications. The OPA4650 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 outstanding choice for many portable, multi-channel and other high-speed applications, where power is at a premium.
