General Description
The MAX5134–MAX5137 is a family of pin-compatible
and software-compatible 16-bit and 12-bit DACs. The
MAX5134/MAX5135 are low-power, quad 16-/12-bit,
buffered voltage-output, high-linearity DACs. The
MAX5136/MAX5137 are low-power, dual 16-/12-bit,
buffered voltage-output, high-linearity DACs. They use
a precision internal reference or a precision external ref-
erence for rail-to-rail operation. The MAX5134–MAX5137
accept a wide +2.7V to +5.25V supply-voltage range to
accommodate most low-power and low-voltage applica-
tions. These devices accept a 3-wire SPI^TM-/QSPI^TM-
/MICROWIRE^TM-/DSP-compatible serial interface to save
board space and reduce the complexity of optically iso-
lated and transformer-isolated applications. The digital
interface’s double-buffered hardware and software
LDAC provide simultaneous output updates. The serial
interface features a READY output for easy daisy-chain-
ing of several MAX5134–MAX5137 devices and/or other
compatible devices. The MAX5134–MAX5137 include a
hardware input to reset the DAC outputs to zero or mid-
scale 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 con-
trol and instrumentation applications. The MAX5134–
MAX5137 are available in an ultra-small (4mm x 4mm),
24-pin TQFN package and are specified over the -40°C
to +105°C extended industrial temperature range.
