REF6125IDGKR General Description

The REF6125IDGKR is part of the REF6000 family of voltage references, designed with integrated low output impedance buffer technology. This feature allows for direct driving of precision data converters without compromising linearity, distortion, and noise performance. Specifically tailored for precision SAR and Delta-Sigma ADCs, the REF6000 family is capable of efficiently supporting the dynamic load imposed during the conversion process. By utilizing a low-output impedance buffer, the voltage reference ensures minimal droop and maintains output voltage within 1LSB (18-bit), even during the initial conversion process when driving the REF pin of compatible ADCs like the ADS8881. This reliability is essential for applications such as burst-mode sampling, event-triggered systems, and variable-sampling-rate data acquisition
