OPA4830 - Quad, Low-Power, Single-Supply, Wideband Operational Amplifier

The OPA4830 is a quad, 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 1.8V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 220mV of either supply while driving 150 . High output drive current (±80mA) and low differential gain and phase errors also make this amplifier an excellent choice for single-supply consumer video products.

Low distortion operation is ensured by the high gain bandwidth product (110MHz) and slew rate (560V/µs), making the OPA4830 an ideal input buffer stage to 3V and 5V CMOS analog-to-digital converters (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 OPA4830 is available in an industry-standard quad pinout TSSOP-14 package.
