SOT-23 (DBV)-6-8.12 mm² 2.9 x 2.8
The OPAx625 family of operational amplifiers are excellent 16-bit and 18-bit, SAR ADC drivers that are high precision with low THD and noise 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). Along with a high dc precision of only 100 µV offset voltage, a wide gain-bandwidth product of 120 MHz, 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: high-drive and low-power. In the innovative low-power mode, the OPAx625 tracks the input signal allowing the OPAx625 to transition from low-power mode to high-drive 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.
