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.

HIGH SLEW RATE: 550V/µs  
LOW INPUT VOLTAGE NOISE: 9.2nV/Hz  
Pb-FREE SOT23 PACKAGE  
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.
