The devices operate from single, 2.7V to 5.5V supply ranges and are guaranteed monotonic by design. The AD3530R also offers a 2.5V, 5ppm/°C internal reference that is disabled by default. The devices include integrated multiplexers that allow monitoring of output voltages, currents, and internal die temperature. The AD3530/AD3530R are available in 2.1mm × 2.2mm, 25-ball WLCSP packages. The devices incorporate power-on reset (POR) circuits that ensure that the DACs output power up to and present at 32kΩ to ground until a valid write is executed. The DACs also contain power-down modes that reduce the current consumption down to 670μA, typical. The serial peripheral interface (SPI) and MICROWIRE®-patible, 4-wire serial interface operates on logic levels as low as 1.08V up to 1.98V and clock rates up to 50MHz. Table 1. Device Family...
