DESCRIPTION
The OPA3832 is a triple, 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 (80MHz) and slew rate (350V/µs), making
the OPA3832 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 OPA3832 is available in an industry-standard
SO-14 package or a small TSSOP-14 package.
