REF60xx/REF61xx High-Precision Voltage References

Texas Instruments REF60xx/REF61xx High-Precision Voltage References are a family of voltage references that has an integrated low output impedance buffer. This buffer enables the user to directly drive the REF pin of precision data converters while preserving linearity, distortion, and noise performance. Most precision SAR and Delta-Sigma ADCs, switch binary-weighted capacitors onto the REF pin during the conversion process. In order to support this dynamic load, the output of the voltage reference must be buffered with a low-output impedance (high-bandwidth) buffer. The REF60xx/REF61xx family devices are well suited, but not limited, to drive the REF pin of the ADS88xx family of SAR ADCs, and ADS127xx family of delta-sigma ADCs, as well as other digital-to-analogue converters (DACs).
