AD5663BRMZ

The AD5663BRMZ is a dual 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC family by Analog Devices. It operates from a single 2.7V to 5.5V supply and draws only 250 µA typical supply current, making it suitable for low-power applications. The device features a string DAC architecture and requires an external voltage reference to set the output range.

Key electrical characteristics include a typical settling time of 7 µs, maximum integral non-linearity (INL) of ±12 LSB, and guaranteed monotonicity by design. The digital interface supports SPI and DSP protocols with a maximum clock frequency of 50 MHz. The DAC includes a power-on reset circuit that can be configured to zero scale or midscale, and hardware LDAC and CLR functions for synchronous updates and clear operations.

The AD5663BRMZ is offered in a 10-lead MSOP package (also compatible with 10-TFSOP) and is rated for an operating temperature range of -40°C to +105°C. Typical power consumption is 1.25 mW at 5V and 0.6 mW at 3V, with a power-down mode consuming only 2.4 µW. This device is designed for process control, data acquisition systems, portable battery-powered instruments, and programmable voltage/current sources.
