EVALUATION KIT AVAILABLE

MAX5138/MAX5139

Low-Power, Single, 16-/12-Bit,

Buffered Voltage-Output DACs

General Description

Features

♦ 16-/12-Bit Resolution in a 3mm x 3mm, 16-Pin

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

TQFN Package

♦ Hardware-Selectable on Power-Up or Reset-to-

Zero/Midscale DAC Output

♦ Double-Buffered Input Registers

♦ LDAC Asynchronously Updates DAC Output

♦ READY Facilitates Daisy Chaining

♦ High-Performance 10ppm/°C Internal Reference

SPI-/QSPI^TM-/MICROWIRE -/DSP-compatible serial

♦ Guaranteed Monotonic Over All Operating

Conditions

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.

♦ Wide +2.7V to +5.25V Supply Range

♦ Rail-to-Rail Buffered Output Operation

♦ Low Gain Error (Less Than 0.5ꢀ FSꢁ and Offset

(Less Than 10mVꢁ

♦ 30MHz 3-Wire SPI-/QSPI-/MICROWIRE-/

DSP-Compatible Serial Interface

♦ CMOS-Compatible Inputs with Hysteresis
