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

less than 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 150Ω. 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 specified by the high

gain bandwidth product (110MHz) and slew rate (560V/µs), making the OPA4830 an

excellent 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.
