The OPA830 is a low-power, single-supply, wideband, voltage-feedback amplifier designed
to operate on a single +5V supply. Operation on ±5V or +10V supplies is also supported. The input
range extends below the negative supply and to within 1.7V of the positive supply. Using
complementary common-emitter outputs provides an output swing to within 25mV of either supply while
driving 150Ω. High output drive current (±80mA) and low differential gain and phase errors also
make them ideal for single-supply consumer video products.
Low distortion operation is ensured by the high gain bandwidth product (110MHz) and slew
rate (550V/µs), making the OPA830 an ideal input buffer stage to 3V and 5V CMOS ADCs. Unlike other
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.
The OPA830 is available in an ultra-small SOT23-5 package.
