The OPAx626 family of operational amplifiers are 16-bit 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). With a high DC precision of only 100 µV offset voltage, a wide
gain-bandwidth product of 120 MHz, and a low wideband noise of 2.5 nV/√Hz,
this family is optimized for driving high-throughput, high-resolution SAR ADCs in applications such
as the ADS88xx
family of SAR ADCs.
The OPAx626 family is available in 5-pin SOT and
8-pin VSSOP packages and is specified for operation from –40°C to +125°C.
