DESCRIPTION
The DAC7554 is a quad-channel, voltage-output DAC
with exceptional linearity and monotonicity. Its pro-
prietary architecture minimizes undesired transients
such as code to code glitch and channel to channel
crosstalk. The low-power DAC7554 operates from a
single 2.7-V to 5.5-V supply. The DAC7554 output
amplifiers can drive a 2-k, 200-pF load rail-to-rail
with 5-µs settling time; the output range is set using
an external voltage reference.
The 3-wire serial interface operates at clock rates up
to 50 MHz and is compatible with SPI, QSPI,
Microwire, and DSP interface standards. The outputs
of all DACs may be updated simultaneously or
sequentially. The parts incorporate a power-on-reset
circuit to ensure that the DAC outputs power up to
zero volts and remain there until a valid write cycle to
the device takes place. The parts contain a
power-down feature that reduces the current con-
sumption of the device to under 1 µA.
The small size and low-power operation makes the
DAC7554 ideally suited for battery-operated portable
applications. The power consumption is typically 3.5
mW at 5 V, 1.65 mW at 3 V, and reduces to 1 µW in
power-down mode.
The DAC7554 is available in a 10-lead MSOP pack-
age and is specified over –40°C to 105°C.

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.
