OPA830-EP Low-Power, Single-Supply, Wideband Operational Amplifier  
1 Features  
3 Description  
The OPA830 is  
a
low-power, single-supply,  
1
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 (VS = +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.
