3 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 150Ω. 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 ultra-small SOT23-5
package.
