REF6245IDGKT, Voltage References 4.5-V, 3-ppm/°C high-precision voltage reference with integrated buffer & enable pin 8-VSSOP -40 to 125

Semiconductors\Power Management ICs\Voltage ReferencesREF6200 High Precision Voltage ReferencesTexas Instruments REF6200 High Precision Voltage References have an integrated low output impedance buffer that enables the user to directly drive the reference (REF) pin of precision data converters. This can be done while preserving linearity, distortion, and noise performance. Most precision SAR and delta-sigma analog-to-digital converters (ADCs) switch binary-weighted capacitors onto the REF pin during the conversion process.
