Description

The OPA2626 operational amplifier is a 16-bit and 18-bit, high-precision, successive-approximation register (SAR) analog-to-digital converter (ADC) driver with low total harmonic distortion (THD) and noise. This op amp 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 device is optimized for driving high-throughput, high-resolution SAR ADCs in applications such as the ADS88xx family of SAR ADCs.

The OPA2626 is available in an 8-pin VSSOP package and is specified for operation from –40°C to +125°C.
