The DAC8551 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
DAC8551 uses a versatile 3-wire serial interface that
operates at clock rates to 30 MHz and is compatible
with standard SPI™, QSPI™, Microwire™, and digital
signal processor (DSP) interfaces.
The DAC8551 requires an external reference voltage
to set its output range. The DAC8551 incorporates a
power-on-reset circuit that ensures the DAC output
powers up at 0 V and remains there until a valid write
takes place to the device. The DAC8551 contains a
power-down feature, accessed over the serial
interface, that reduces the current consumption of the
device to 200 nA at 5 V.
• Available Package:
– 3 mm × 5 mm MSOP-8
APPLICATIONS
• Process Control
The low-power consumption of this device in normal
operation makes it ideally suited for portable battery-
operated equipment. The power consumption is
1.00 mW at 5 V, reducing to 1 µW in power-down
DataSheet4mU.ocdoem.
• Data Acquisition Systems
The DAC8551 is available in an MSOP-8 package.
• Closed-Loop Servo-Control
• PC Peripherals
• Portable Instrumentation
• Programmable Attenuation
