DESCRIPTION
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.
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.
