Overview
The AD5660CRMZ-3REEL7, 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 requiring accurate analog output.
The AD5660 features an on-chip, 2.5 V, 5 ppm/°C reference, which provides a full-scale output voltage range of 5 V. It also includes a power-on reset circuit that ensures the DAC output powers up to midscale and remains there until a valid write takes place. The device is available in an 8-lead MSOP package and operates over a temperature range of -40°C to 105°C.
