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.
