The MAX5158/MAX5159 low-power, serial, voltage-

output, dual, 10-bit digital-to-analog converters (DACs)

consume only 500µA from a single +5V (MAX5158) or

+3V (MAX5159) supply. These devices feature Rail-to-

Rail

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 double-

buffered 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 pro-

grammable 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.
