Overview
The DAC60501ZDGSR is a highly accurate, low-power digital-to-analog converter (DAC) produced by Texas Instruments. This 12-bit DAC is part of the DACx0501 family, which includes 16-bit and 14-bit variants. The DAC60501ZDGSR is known for its voltage-output and is available in a 10-pin VSSOP (DGS) package. It features a precision internal reference and supports both SPI and I2C serial interfaces. The device is designed for low power consumption, with a typical current draw of 1 mA at 5.5 V and a power-down mode that reduces current to 15 µA. The DAC60501ZDGSR operates over a wide temperature range of –40°C to +125°C, making it suitable for various industrial and commercial applications.
