GENERAL DESCRIPTION

The AD3530/AD3530R are low power, 8-channel, 16-bit, buffered

voltage output, digital-to-analog converters (DACs) that include

software-programmable gain controls that result in full-scale output

spans of 2.5V or 5V for reference voltages of 2.5V. The devices op-

erate 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 monitor-

ing 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®-compatible,

4-wire serial interface operates on logic levels as low as 1.08V up

to 1.98V and clock rates up to 50MHz.
