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

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
