Overview
The AD5620CRMZ-1, produced by Analog Devices Inc., is a member of the nanoDAC™ family of devices. It is a low-power, single, 12-bit, buffered voltage-out digital-to-analog converter (DAC). This device is known for its high precision and low power consumption, making it suitable for a variety of applications. The AD5620CRMZ-1 features an internal 1.25 V or 2.5 V reference with a 5 ppm/°C temperature coefficient, ensuring stable output voltage ranges of 2.5 V or 5 V respectively. It is available in an 8-lead MSOP package, which is compact and convenient for space-constrained designs.
