OPA646  
Low Power, Wide Bandwidth  
OPERATIONAL AMPLIFIER  
FEATURES  
DESCRIPTION  
LOW POWER: 55mW  
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.  
UNITY-GAIN BANDWIDTH: 650MHz  
UNITY-GAIN STABLE  
FAST 12-BIT SETTLING: 15ns (0.01%)  
LOW INPUT BIAS CURRENT: 2µA  
LOW HARMONICS: –82dBc at 5MHz  
LOW DIFFERENTIAL GAIN/PHASE  
ERRORS: 0.025%/0.08°  
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.
