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 supported. 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 supply. The high output drive
current and low differential gain and phase errors also make
it ideal for single-supply 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 improves as the signal swing is
decreased. A low 9.3nV/√Hz input voltage noise supports
wide dynamic range operation.
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.
