General Description
The MAX5138/MAX5139 are a family of single-channel
pin-compatible and software-compatible 16-bit and 12-
bit DACs. The MAX5138/MAX5139 are low-power, 16-
bit/12-bit, buffered voltage-output, high-linearity DACs.
They use a precision internal reference or a precision
external reference for rail-to-rail operation. The
MAX5138/MAX5139 accept a wide +2.7V to +5.25V sup-
ply-voltage range to accommodate most low-power and
low-voltage applications. These devices accept a 3-wire
SPI-/QSPITM-/MICROWIRE-/DSP-compatible serial
interface to save board space and reduce the complexi-
ty of optically isolated and transformer-isolated applica-
tions. The digital interface’s double-buffered hardware
and software LDAC provide simultaneous output update.
The serial interface features a READY output for easy
daisy-chaining of several MAX5138/MAX5139 devices
and/or other compatible devices. The MAX5138/MAX5139
include a hardware input to reset the DAC outputs to
zero or midscale upon power-up or reset, providing
additional safety for applications that drive valves or
other transducers that need to be off during power-up.
The high linearity of the DACs makes these devices ideal
for precision control and instrumentation applications.
The MAX5138/MAX5139 are available in an ultra-small
(3mm x 3mm), 16-pin TQFN package and are specified
over the -40°C to +105°C extended industrial tempera-
ture range.
