General Description
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.
The 3-wire serial interface is compatible with SPI™,
QSPI™, and MICROWIRE™ standards. An input regis-
ter 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 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 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.
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.
