General Description

The MAX5174/MAX5176 low-power, serial, voltage-out-

put, 12-bit digital-to-analog converters (DACs) feature a

precision output amplifier in a space-saving 16-pin

QSOP package. The MAX5174 operates from a single

+5V supply, and the MAX5176 operates from a single

+3V supply. Both devices draw only 280µA of supply

current, which reduces to 1µA in shutdown. In addition,

the programmable power-up reset feature allows for a

user-selectable output voltage state of either 0 or mid-

scale.

The 3-wire, digital, serial interface is compatible with

SPI™/QSPI™, and MICROWIRE™ standards. An input

buffered input, allowing the input and DAC registers to

be updated independently or simultaneously with a 16-

bit serial word. Additional features include software and

hardware shutdown, shutdown lockout, a hardware

clear pin, and a reference input capable of accepting

DC and offset AC signals. These devices provide a pro-

grammable digital output pin for added functionality

and a serial-data output pin for daisy-chaining. All logic

inputs are TTL/CMOS compatible and are internally

buffered with Schmitt triggers to allow direct interfacing

to optocouplers.

The MAX5174/MAX5176 incorporate a proprietary on-

chip circuit that keeps the output voltage virtually

“glitch free,” limiting the glitches to a few millivolts dur-

ing power-up.

Both devices are available in 16-pin QSOP packages

and are specified for the extended (-40°C to +85°C)

temperature range. The MAX5170/MAX5172 are pin-

compatible 14-bit upgrades to the MAX5174/MAX5176.

For 100% pin-compatible DACs with internal reference,

see the 13-bit MAX5130/MAX5131 and the 12-bit

MAX5120/MAX5121 data sheets.
