Description for the OPA843
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 combination 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.
