MAX5139GTE+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P17
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-/QSPI
TM
-/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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
