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/µs), 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.
