8.4.1 High-Drive Mode

The OPA2626 has a 120-MHz gain bandwidth, 2.5-nV/√Hz input-referred noise, and consumes 2 mA of quiescent current. Additionally, the OPA2626 has an offset voltage of 100 µV (maximum) and an offset voltage drift of 1 µV/°C (typical). This combination of high precision, high speed, and low noise makes this device suitable for use as an input driver for high-precision, high-throughput SAR ADCs such as the ADS88xx family of SAR ADCs, as illustrated in Figure 61.
