DESCRIPTION
The OPA830 is a 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 1.7V of the positive supply. Using
complementary common-emitter outputs provides an output
swing to within 25mV of either supply while driving 150. 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 industry-standard SO-8
package. The OPA830 is also available in an ultra-small
SOT23-5 package. For fixed-gain line driver applications,
consider the OPA832.
