SBOS655 –MARCH 2014

OPA830-EP Low-Power, Single-Supply, Wideband Operational Amplifier

1 Features

3 Description

The OPA830 is

low-power, single-supply,

•

High Bandwidth:

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.

–

250MHz (G = +1)

110MHz (G = +2)

•

Low Supply Current:

3.9mA (V_S= +5V)

Flexible Supply Range:

–

±1.4V to ±5.5V Dual Supply

+2.8V to +11V Single Supply

•

Input Range Includes Ground On Single Supply

4.88V Output Swing on +5V Supply

High Slew Rate: 550V/μs

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-

performance improves as the signal swing is

decreased. A low 9.2nV/√Hz input voltage noise

supports wide dynamic range operation.
