Introduction

AI Translation

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 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, such as the ADS88xx family of SAR ADCs. The OPAx625 features two operating modes: highdrive and low-power. In the innovative low-power mode, the OPAx625 tracks the input signal allowing the device to transition from low-power mode to highdrive mode at 16-bit ENOB within 170 ns. The OPAx625 family is available in 6-pin SOT and 10-pin VSSOP packages and is specified for operation from -40°C to +125°C.
