MAX5104CEE Datasheet MAX5104CEE+T, MAX5104CEE, MAX5104EEE | P1-P3

General Description

The MAX5104 low-power, serial, voltage-output, dual

12-bit digital-to-analog converter (DAC) consumes only

500µA from a single +5V supply. This device features

Rail-to-Rail

output swing and is available in a space-

saving 16-pin QSOP package. To maximize the dynamic

range, the DAC output amplifiers are configured with an

internal gain of +2V/V.

The 3-wire serial interface is SPI™/QSPI™/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 programmable power-

down (2µA), hardware power-down lockout (PDL), 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.

These devices 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.
