MAX5259EEE+T

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P20
General Description
The MAX5258/MAX5259 are +3V/+5V single-supply,
digital serial-input, voltage-output, 8-bit octal digital-to-
analog converters (DACs). Internal precision buffers
swing Rail-to-Rail
®
, and the reference input range
extends from ground to the positive supply. The +5V
(MAX5258) and the +3V (MAX5259) feature a 10µA
(max) shutdown mode.
The serial interface is double-buffered. A 16-bit input
shift register is followed by eight 8-bit input registers
and eight 8-bit DAC registers. The 16-bit serial word
consists of two “don’t care” bits, three address bits,
three control bits, and eight data bits. The input and
DAC registers can both be updated independently or
simultaneously with a single software command. The
asynchronous control input (LDAC) provides simultane-
ous updating of all eight DAC registers.
The interface is compatible with SPI™, QSPI™ (CPOL =
CPHA = 0 or CPOL = CPHA = 1), and MICROWIRE™.
A buffered digital data output allows daisy-chaining of
serial devices.
The MAX5258/MAX5259 are available in a 16-pin QSOP
package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
