General Description

The MAX5175/MAX5177 low-power, serial, voltage-out­put, 12-bit digital-to-analog converters (DACs) feature a
precision output amplifier in a space-saving 16-pin
QSOP package. The MAX5175 operates from a single
+5V supply, and the MAX5177 operates from a single
+3V supply. The output amplifier’s inverting input is
available to allow specific gain configurations, remote
sensing, and high output current capability. This makes
the MAX5175/MAX5177 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 feature allows for a user­selectable output voltage state 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 registers to be updated independent­ly or simultaneously with a 16-bit serial word. Additional
features include software and hardware shutdown, shut­down lockout, a hardware reset pin, and a reference
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 triggers
to allow direct interfacing to optocouplers.

The MAX5175/MAX5177 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 come in 16-pin QSOP packages and are
specified for the extended (-40°C to +85°C) temperature
range. The MAX5171/MAX5173 are 14-bit pin-compatible
upgrades to the MAX5175/MAX5177. For pin-compatible
DACs with an internal reference, see the 13-bit
MAX5132/MAX5133 and 12-bit MAX5122/MAX5123.
