Fe a t u re s

The MAX5171/MAX5173 low-power, serial, voltage-output,

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

sion output amplifier in a space-saving 16-pin QSOP

package. The MAX5171 operates from a +5V single sup-

ply, and the MAX5173 operates from a +3V single supply.

The output amplifier’s inverting input is available to allow

specific gain configurations, remote sensing, and high

output current capability. This makes the MAX5171/

MAX5173 ideal for a wide range of applications, including

industrial process control. Both devices draw only 260µA

of supply current, which reduces to 1µA in shutdown

mode. In addition, the programmable power-up reset fea-

ture allows for a user-selectable output voltage of either 0

or midscale.

♦ ±1 LSB INL

♦ 1µA Shutdown Current

♦ “Glitch Free” Output Voltage at Power-Up

♦ Single-Supply Operation: +5V (MAX5171)

+3V (MAX5173)

♦ Full-Scale Output Range:

+2.048V (MAX5173, V

+4.096V (MAX5171, V

♦ Rail-to-Rail^®Output Amplifier

= +1.25V)

= +2.5V )

REF

♦ Low THD (-80dB) in Multiplying Operation

♦ SPI/QSPI/MICROWIRE-Compatible 3-Wire

Serial Interface

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

QSPI™, and MICROWIRE™ standards. An input register

followed by a DAC register provides a double-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 shut-

down, shutdown lockout, a hardware clear pin, and a ref-

erence input capable of accepting DC and offset AC

signals. These devices provide a programmable 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 trig-

gers to allow direct interfacing to optocouplers.

♦ Programmable Shutdown Mode and Power-Up

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

♦ User-Programmable Digital Output Pin Allows

Serial Control of External Components

♦ Pin-Compatible Upgrade to the 12-Bit

Ord e rin g In fo rm a t io n

The MAX5171/MAX5173 incorporate a proprietary on-chip

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

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

Both devices are available in 16-pin QSOP packages and

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

ture range. The MAX5171/MAX5173 are pin-compatible

upgrades to the 12-bit MAX5175/MAX5177. For 100% pin-

compatible DACs with an internal reference, see the 13-bit

MAX5132/MAX5133 and the 12-bit MAX5122/MAX5123
