OPA2626
Description
The OPAx626 family of operational amplifiers are 16bit and 18-bit, high-precision, SAR ADC drivers with low total harmonic distortion (THD) and noise. This family of precision op amps 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).
