Available Packages:
The DAC8550 is a small, low-power, voltage output,
16-bit digital-to-analog converter (DAC). It is
monotonic, provides good linearity, and minimizes
undesired code to code transient voltages. The
DAC8550 uses a versatile 3-wire serial interface that
operates at clock rates of up to 30 MHz and is
compatible with standard SPI™, QSPI™,
Microwire™, and digital signal processor (DSP)
interfaces.
The DAC8550 requires an external reference voltage
to set its output range. The DAC8550 incorporates a
power-on reset circuit that ensures that the DAC
output powers up at midscale and remain there until a
valid write takes place to the device. The DAC8550
contains a power-down feature, accessed over the
serial interface, that reduces the current consumption
of the device to 200 nA at 5 V.
– 3 mm × 5 mm MSOP-8
APPLICATIONS
Process Control
The low-power consumption of this device in normal
operation makes it ideal for portable battery-operated
DataSheet4eUq.cuoipmment. Power consumption is 1 mW at 5 V,
reducing to 1 µW in power-down mode.
Data Acquisition Systems
The DAC8550 is available in a MSOP-8 package.
Closed-Loop Servo-Control
PC Peripherals
