MIKROE-6638

MIKROE-6638 is a VREF Click compact add-on board designed to provide a stable and accurate voltage reference for low-power, noise-sensitive applications. This board features the REF34xx series from Texas Instruments, a high-precision CMOS voltage reference. Key features include ultra-low temperature drift of 6ppm/°C, initial accuracy of ±0.05%, low power consumption under 95µA, and output noise as low as 3.8μVp-p/V. The board supports 3V voltage versions, with a ±10mA output current and excellent long-term stability. Thanks to the Click Snap feature, size, weight, and power consumption can be reduced for final-phase prototyping. Typical use cases include data acquisition systems, high-resolution ADC/DAC designs, and both positive and negative voltage reference applications.
