DESCRIPTION

The OPA2631 is a dual, low power, voltage-feedback

amplifier designed to operate on a single +3V or +5V

supply. Operation on 5V or +10V supplies is also

supported. The input range extends below ground and

to within 1V of the positive supply. Using complemen-

tary common-emitter outputs provides an output swing

to within 30mV of ground and 130mV of the positive

supply. The high output drive current and low differen-

tial gain and phase errors also make it ideal for single-

supply consumer video products.

Low distortion operation is ensured by the high gain

bandwidth (68MHz) and slew rate (100V/ s), making

the OPA2631 an ideal input buffer stage to 3V and 5V

CMOS converters. Unlike other low power, single-

supply amplifiers, distortion performance improves as

the signal swing is decreased. A low 6nV/ Hz input

voltage noise supports wide dynamic range operation.

The OPA2631 is available in an industry standard

SO-8 package. Where a single channel, single-supply

operational amplifier is required, consider the OPA631

and OPA632. Where higher full-power bandwidth and

lower distortion are required, consider the OPA2634.
