Texas Instruments  OPA830IDBVT

The OPA830 is a low-power, single-supply, wideband, voltage-feedback amplifier designed to operate on a single +3V or +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 150. 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 industry-standard SO-8 package. The OPA830 is also available in an ultra-small SOT23-5 package. For fixed-gain line driver applications, consider the OPA832.
