Low-Cost / +5V / Serial-Input / Voltage-Output / 14-Bit DAC
General DescriptionThe MAX5544 serial-input, voltage-output, 14-bit
monotonic digital-to-analog converter (DAC) operates
from a single +5V supply. The DAC output is
unbuffered, resulting in low 0.3mA supply current and
low 1LSB offset error. The DAC output range is 0V to
VREF. The DAC latch accepts a 16-bit serial word. A
power-on reset circuit clears the DAC output to 0V
(unipolar mode) when power is initially applied.
The 10MHz 3-wire serial interface is SPI™/QSPI™/
MICROWIRE™compatible and interfaces directly with
optocouplers for applications requiring isolation. The
MAX5544 is available in an 8-pin SO package.

MAX5544
Low-Cost, +5V, Serial-Input,
Voltage-Output, 14-Bit DAC--
Detailed DescriptionThe MAX5544 voltage-output, 14-bit digital-to-analog
converter (DAC) offers 14-bit monotonicity with less
than 1LSB differential linearity error. Serial-data transfer
minimizes the number of package pins required.
The MAX5544 is composed of two matched DAC sec-
tions, with a 12-bit inverted R-2R DAC forming the
12LSBs and the 4MSBs derived from 15 identically
matched resistors. This architecture allows the lowest
glitch energy to be transferred to the DAC output on
major-carry transitions. It also decreases the DAC out-
put impedance by a factor of eight compared to a stan-
dard R-2R ladder, allowing unbuffered operation in
medium-load applications. Figure 1 is the timing dia-
gram.
Digital InterfaceThe MAX5544 digital interface is a standard 3-wire con-
nection compatible with SPI/QSPI/MICROWIRE inter-
faces. The chip-select input (CS) frames the serial data
loading at the data input pin (DIN). Immediately follow-
ing CS’s high-to-low transition, the data is shifted
synchronously and latched into the input register on the
rising edge of the serial-clock input (SCLK). After 16
data bits (14 data bits, plus two sub-bits set to zero)
have been loaded into the serial input register, it trans-
fers its contents to the DAC latch on CS’s low-to-high
transition (Figure 2). Note that if CSdoes not remain
low during the entire 16 SCLK cycles, data will be cor-
rupted. In this case, reload the DAC latch with a new
16-bit word.
External ReferenceThe MAX5544 operates with external voltage refer-
ences from 2V to 3V. The reference voltage determines
the DAC’s full-scale output voltage.
Power-On ResetThe MAX5544 has a power-on reset circuit to set the
DAC’s output to 0V in unipolar mode when VDDis first
applied. This ensures that unwanted DAC output volt-
ages will not occur immediately following a system
power-up, such as after power loss. In bipolar mode,
the DAC output is set to -VREF.
