Detailed Description
The MAX5541 voltage-output, 16-bit digital-to-analog
converter (DAC) offers 16-bit monotonicity with less
than 1LSB differential linearity error. Serial-data transfer
minimizes the number of package pins required.
The MAX5541 is composed of two matched DAC sec-
tions, with a 12-bit inverted R-2R DAC forming the 12
LSBs and the 4 MSBs 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
Diagram.
Digital Interface
The MAX5541 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 have been loaded into the serial input regis-
ter, it transfers its contents to the DAC latch on
CS
’s
low-to-high transition (Figure 2). Note that if
CS
does
not remain low during the entire 16 SCLK cycles, data
will be corrupted. In this case, reload the DAC latch
with a new 16-bit word.
External Reference
The MAX5541 operates with external voltage refer-
ences from 2V to 3V. The reference voltage determines
the DAC’s full-scale output voltage.
Power-On Reset
The MAX5541 has a power-on reset circuit to set the
DAC’s output to 0V in unipolar mode when V
DD
is 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 -V
REF
