OPA2832 双通道低功耗高速固定增益运算放大器

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.
