7 Detailed Description

7.1 Overview

The OPA830 is a unity-gain stable, very high-speed voltage-feedback op amp designed for single-supply

operation (+5V to +10V). The input stage supports input voltages below ground and to within 1.7V of the positive

supply. The complementary common-emitter output stage provides an output swing to within 25mV of ground

and the positive supply. The OPA830 is compensated to provide stable operation with a wide range of resistive

loads.

7.3 Feature Description

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 150

Ω. High output drive current (±80mA)

and low differential gain and phase errors also make them ideal for single-supply consumer video products.
