Overview
The DAC80501MDGST is a highly accurate, low-power digital-to-analog converter (DAC) produced by Texas Instruments. This 16-bit DAC is part of the DACx0501 family, which includes 14-bit and 12-bit versions. The DAC80501 is specified monotonic by design and offers linearity of less than 1 LSB. It features a 2.5-V, 5-ppm/°C internal reference, providing full-scale output voltage ranges of 1.25 V, 2.5 V, or 5 V. The device is designed for low power consumption, with a typical current of 1 mA at 5.5 V and a power-down mode that reduces current to 15 µA at 5 V.
