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.

APPLICATIONS

● TELECOMMUNICATIONS

● MEDICAL IMAGING

● CCD IMAGING

● PORTABLE EQUIPMENT

● ACTIVE FILTERS

● VIDEO AMPLIFICATION

● ADC/DAC GAIN AMPLIFIER

● HIGH SPEED INTEGRATORS
