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

/MICROWIRE

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 or a 16-pin TSSOP package. Both

packages are specified over the -40°C to +105°C

extended industrial temperature range.
