The OPA2830ID is a dual low-power wideband voltage-feedback Operational Amplifier for use with PLL integrators. The input range extends below ground and to within 1.8V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 25mV of ground and +VS while driving 150R. High output drive current (75mA) 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 (100MHz) and slew rate (500V/μs), making the OPA2830 an ideal input buffer stage to 3 and 5V CMOS analog-to-digital converters (ADCs). Unlike earlier low-power, single-supply amplifiers, distortion performance improves as the signal swing is decreased. A low 9.2nV/√Hz input voltage noise supports wide dynamic range operation.
