Overview
The DAC60501MDGSR from Texas Instruments is a highly accurate, low-power 12-bit digital-to-analog converter (DAC) with voltage-output. This device is part of the DACx0501 family, which includes the DAC80501 and DAC70501, offering different resolutions. The DAC60501 is specified monotonic by design and provides linearity of less than 1 LSB. It features an integrated 2.5-V precision reference with a temperature coefficient of 5 ppm/°C, ensuring high accuracy across a wide temperature range.
The device operates with a wide power supply range of 2.7 V to 5.5 V and consumes a low current of 1 mA at 5.5 V. It also includes a power-down feature that reduces current consumption to typically 15 µA at 5 V. The DAC60501 is available in small 8-pin WSON and 10-pin VSSOP packages, making it suitable for space-constrained applications.
