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.
