DESCRIPTION

The OPA2832 is a dual, low-power, high-speed,

fixed-gain amplifier designed to operate on a single

+3V to +11V supply. Operation on ±1.5V to ±5.5V

supplies is also supported. The input range extends below ground and to within 1.7V of the positive

supply.

Using complementary common-emitter outputs

provides an output swing to within 30mV of ground

and 60mV 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 high bandwidth

product (75MHz) and slew rate (350V/ms), making the

OPA2832 an ideal input buffer stage to 3V and 5V

CMOS converters. Unlike earlier 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 OPA2832 is available in an industry-standard

SO-8 package or a small MSOP-8 package. For

gains other than +1, –1, or +2, consider the

OPA2830.
