The MAX533 serial-input, voltage-output, 8-bit quad
digital-to-analog converter (DAC) operates from a sin-
gle +2.7V to +3.6V supply. Internal precision buffers
swing rail to rail, and the reference input range includes
both ground and the positive rail. The MAX533 features
a 1µA shutdown mode.
The serial interface is double buffered: a 12-bit input
shift register is followed by four 8-bit buffer registers
and four 8-bit DAC registers. The 12-bit serial word
consists of eight data bits and four control bits (for DAC
selection and special programming commands). Both
the input and DAC registers can be updated indepen-
dently or simultaneously with a single software com-
mand. Two additional asynchronous control pins, LDAC
and CLR, provide simultaneous updating or clearing of
the input and DAC registers.
The interface is compatible with SPI™, QSPI™ (CPOL =
CPHA = 0 or CPOL = CPHA = 1), and Microwire™. A
buffered data output allows daisy chaining of serial
devices.
In addition to 16-pin DIP and CERDIP packages, the
MAX533 is available in a 16-pin QSOP that occupies
the same area as an 8-pin SO.
