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.

(1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not supported.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
