DESCRIPTION

The DAC8552 is a 16-bit, dual channel, voltage

output digital-to-analog converter (DAC) offering low

power operation and a flexible serial host interface.

Each on-chip precision output amplifier allows rail-to-rail output swing to be achieved over the

supply range of 2.7V to 5.5V. The device supports a

standard 3-wire serial interface capable of operating

with input data clock frequencies up to 30MHz for

VDD = 5V.

The DAC8552 requires an external reference voltage to set the output range of each DAC channel. Also

incorporated into the device is a power-on reset

circuit which ensures that the DAC outputs power up

at zero-scale and remain there until a valid write

takes place. The DAC8552 provides a flexible

power-down feature, accessed over the serial

interface, that reduces the current consumption of

the device to 700nA at 5V.

The low-power consumption of this device in normal

operation makes it ideally suited for portable,

battery-operated equipment and other low-power

applications. The power consumption is 0.5mW per

channel at 2.7V, reducing to 1mW in power-down

mode.

The DAC8552 is available in a MSOP-8 package

with a specified operating temperature range of

–40°C to +105°C.
