16-BIT, ULTRA-LOW GLITCH, VOLTAGE OUTPUT
DIGITAL-TO-ANALOG CONVERTER
Relative Accuracy: 3LSB
The DAC8551 is a small, low-power, voltage output,
16-bit
digital-to-analog
converter
(DAC).
It
is
Glitch Energy: 0.1nV-s
monotonic, provides good linearity, and minimizes
MicroPower Operation:
undesired
code-to-code
transient
voltages.
The
140
A at 2.7V
DAC8551 uses a versatile 3-wire serial interface that
Power-On Reset to Zero
operates at clock rates to 30MHz and is compatible
with standard SPI, QSPI, Microwire, and
Power Supply: +2.7V to +5.5V
digital signal processor (DSP) interfaces.
16-Bit Monotonic Over Temperature
The DAC8551 requires an external reference voltage
Settling Time: 10
s to ±0.003% FSR
to set its output range. The DAC8551 incorporates a
Low-Power Serial Interface with
power-on-reset circuit that ensures the DAC output

powers up at 0V and remains there until a valid write

takes place to the device. The DAC8551 contains a
Rail-to-Rail Operation
power-down
feature,
accessed
over
the
serial
interface, that reduces the current consumption of
Power-Down Capability
the device to 200nA at 5V.
Binary Input
The low-power consumption of this device in normal
SYNC Interrupt Facility
operation makes it ideally suited for portable, battery-
Drop-In Compatible With DAC8531/01
operated equipment. The power consumption is

0.38mW at 2.7V, reducing to less than 1
W in
power-down mode.
Available in a Tiny MSOP-8 Package
The DAC8551 is available in an MSOP-8 package.
For additional flexibilty, see the DAC8550, a 2's

complement-input counterpart to the DAC8551.
