Overview
The AD5660ARJZ-2REEL7, produced by Analog Devices Inc., is a member of the nanoDAC™ family of devices. It is a low-power, single, 16-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 AD5660 features an on-chip precision 2.5 V reference with a temperature coefficient of 5 ppm/°C, ensuring stable output voltage. It operates on a single 3 V or 5 V power supply and includes a power-on reset circuit that sets the output to 0 V or midscale until a valid write occurs. The device also includes multiple power-down modes to reduce current consumption significantly.
