APPLICATIONS

DESCRIPTION

The OPA832 is a low-power, high-speed, fixed-gain

amplifier designed to operate on a single +3.3V or +5V

supply. Operation on

±5V or +10V supplies is also sup-

ported. The input range extends below ground and to

within 1V of the positive supply. Using complementary

common-emitter outputs provides an output swing to

within 30mV of ground and 130mV of the positive sup-

ply. The high output drive current and low differential

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

ply consumer video products.

Low distortion operation is ensured by the high gain

bandwidth product (200MHz) and slew rate (850V/

µs),

making the OPA832 an ideal input buffer stage to 3V

and 5V CMOS converters. Unlike other low-power,

single-supply amplifiers, distortion performance im-

proves as the signal swing is decreased. A low 9.3nV/

√

Hz input voltage noise supports wide dynamic range op-

eration.

The OPA832 is available in an industry-standard SO-8

package. The OPA832 is also available in an ultra-small

SOT23-5 package. For gains other than +1, −1, or +2,

consider using the OPA830.
