OPA625 Overview
The OPAx625 family of operational amplifiers are excellent 16-bit and 18-bit, high-precision, SAR ADC drivers with low THD and noise that allow for a unique power-scalable solution. This family of devices is fully characterized and specified with a 16-bit settling time of 280 ns that enables a true 16-bit effective number of bits (ENOB). With a high dc precision of only 100 µV offset voltage, a wide gainbandwidth...
