General Desc ription
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.
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.
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
data sheets.
