P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
_______________General Description
The MAX534 serial-input, voltage-output, 8-bit quad dig-
ital-to-analog converter (DAC) operates from a single
+4.5V to +5.5V supply. Internal precision buffers swing
rail to rail, and the reference input range includes both
ground and the positive rail. The MAX534 features a
2.5µA 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 independently or
simultaneously with a single software command. 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
MAX534 is available in a 16-pin QSOP that occupies the
same area as an 8-pin SO.
For operation guaranteed to 2.7V, see the MAX533
data sheet.
