Rainbow Electronics MAX5159 User Manual

_______________General Description

The MAX5158/MAX5159 low-power, serial, voltage­output, dual, 10-bit digital-to-analog converters (DACs)
consume only 500µA from a single +5V (MAX5158) or
+3V (MAX5159) supply. These devices feature Rail-to­Rail

®

output swing and are available in a space-saving
16-pin QSOP package. To maximize dynamic range, the
DAC output amplifiers are configured with an internal gain
of +2V/V.

The 3-wire serial interface is SPI™/QSPI™ and
Microwire™ compatible. Each DAC has a double­buffered input organized as an input register followed by
a DAC register, which allows the input and DAC registers
to be updated independently or simultaneously with a
16-bit serial word. Additional features include a 2µA pro­grammable shutdown, hardware-shutdown lockout, a
separate reference-voltage input for each DAC that
accepts AC and DC signals, and an active-low clear input
(

CL) that resets all registers and DACs to zero. The
MAX5158/MAX5159 provide a programmable logic pin
for added functionality and a serial-data output pin for
daisy chaining.

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.
