Product Introduction

The OPA843 offers an unprecedented level of speed and dynamic range for a monolithic op-amp. Using a high gain bandwidth (GBW), two gain stage design, the OPA843 gives the device an excellent dynamic range of gain. The "classic" differential input complements this band with high DC accuracy beyond the dynamic range of most high-speed amplifier products. The combination of extremely low input offset voltage and current, high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) and high open-loop gain gives interception to a high-order DC precision amplifier with low noise.

The 12-to-16-bit converter interface will benefit from a combination of these features. High-speed resistive applications allow for superior DC accuracy as well as:
