SBOS268C – DECEMBER 2002 – DECEMBER 2008  
Wideband, Low Distortion, Medium Gain,  
Voltage-Feedback OPERATIONAL AMPLIFIER  
DESCRIPTION  
FEATURES  
The OPA843 provides a level of speed and dynamic range  
previously unattainable in a monolithic op amp. Using a high  
Gain Bandwidth (GBW), two gain-stage design, the OPA843  
gives a medium gain range device with exceptional dynamic  
range. The “classic” differential input complements this high  
dynamic range with DC precision beyond most high-speed  
amplifier products. Very low input offset voltage and current,  
high Common-Mode Rejection Ratio (CMRR) and Power-  
Supply Rejection Ratio (PSRR), and high open-loop gain  
combine to give a high DC precision amplifier along with low  
noise and high 3rd-order intercept.  
● HIGH BANDWIDTH: 260MHz (G = +5)  
● GAIN BANDWIDTH PRODUCT: 800MHz  
● LOW INPUT VOLTAGE NOISE: 2.0nV/√Hz  
● VERY LOW DISTORTION: –96dBc (5MHz)  
● HIGH OPEN-LOOP GAIN: 110dB  
● FAST 12-BIT SETTLING: 10.5ns (0.01%)  
● LOW INPUT OFFSET VOLTAGE: 300µV  
● OUTPUT CURRENT: ±100mA  
12- to 16-bit converter interfaces will benefit from this combi-  
nation of features. High-speed transimpedance applications  
can be implemented with exceptional DC precision as well.  
Differential configurations using two OPA843s can deliver  
very low distortion to high output voltages, as shown below.  
APPLICATIONS  
● ADC/DAC BUFFER AMPLIFIER  
● LOW DISTORTION “IF” AMPLIFIER  
● ACTIVE FILTERS  
● LOW-NOISE RECEIVER
