REF6133IDGKT Descrizione generale

The REF6133IDGKT is a versatile voltage reference from the REF6000 family, designed to drive precision data converters with its integrated low output impedance buffer. This feature allows for optimal performance in SAR and Delta-Sigma ADCs, ensuring linearity, distortion, and noise control during the conversion process. With a high-bandwidth buffer, the REF6133IDGKT can effectively support the dynamic load of the REF pin, making it compatible with a range of ADCs and DACs. Moreover, its ability to maintain output voltage within 1LSB (18-bit) with minimal droop is particularly advantageous for applications requiring burst-mode or event-triggered sampling. The REF6133IDGKT boasts a maximum temperature drift of just 8 ppm/°C and initial accuracy of 0.05%, making it a reliable choice for temperature-sensitive systems. For detailed comparisons with other REF6000 variants, refer to the Device Comparison Table
