The MAX5170/MAX5172 low-power, serial, voltage-out-

put, 14-bit digital-to-analog converters (DACs) feature a

precision output amplifier in a space-saving 16-pin

QSOP package. The MAX5170 operates from a +5V

single supply and the MAX5172 operates from a +3V

single 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 power-up output voltage of either 0 or

midscale.

♦ ±1 LSB INL

♦ 1µA Shutdown Current

♦ “Glitch Free” Output Voltage at Power-Up

♦ Single-Supply Operation

♦ Full-Scale Output Range

The 3-wire serial interface is compatible with SPI™,

QSPI™, and MICROWIRE™ standards. An input regis-

te r followe d b y a DAC re g is te r p rovid e s a d oub le -

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.

♦ Rail-to-Rail^®Output Amplifier

♦ Adjustable Output Offset

♦ Low THD (-80dB) in Multiplying Operation

♦ SPI/QSPI/MICROWIRE-Compatible 3-Wire

Serial Interface

♦ Programmable Shutdown Mode and Power-Up

Reset (0 or Midscale)

♦ Buffered Output Capable of Driving 5kΩ || 100pF

Loads

♦ User-Programmable Digital Output Pin Allows

Serial Control of External Components

The MAX5170/MAX5172 incorporate a proprietary on-chip

circuit that keeps the output voltage virtually “glitch free,”

limiting the glitches to a few millivolts during power-up.

♦ Pin-Compatible Upgrade to the 12-Bit

MAX5174/MAX5176

Both devices are available in 16-pin QSOP packages and

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

ture range. For 100% pin-compatible DACS with internal

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

bit MAX5120/MAX5121 data sheets.
