19-1446; Rev 1; 3/04

+5V/+3V, 12-Bit, Serial, Force/Sense DACs

with 10ppm/°C Internal Reference

General Description

Features

The MAX5122/MAX5123 low-power, 12-bit, voltage-out-

put, digital-to-analog converters (DACs) feature an inter-

nal precision bandgap reference and output amplifier.

♦ Single-Supply Operation

+5V (MAX5122)

+3V (MAX5123)

The MAX5122 operates on a single +5V supply with an

internal +2.5V reference, and offers a configurable output

amplifier. If necessary, the user can override the on-chip,

<10ppm/°C voltage reference with an external reference.

The MAX5123 has the same features as the MAX5122 but

operates from a single +3V supply and has an internal

+1.25V precision reference. The user-accessible inverting

input and output of the amplifier allows specific gain con-

figurations, remote sensing, and high output drive capa-

bility for a wide range of force/sense applications. Both

devices draw only 500µA of supply current, which

reduces to 3µA in power-down mode. In addition, their

power-up reset feature allows for a user-selectable initial

output state of either 0V or midscale and reduces output

glitches during power-up.

♦ Built-In 10ppm/°C max Precision Bandgap Reference

+2.5V (MAX5122)

+1.25V (MAX5123)

♦ SPI/QSPI/MICROWIRE-Compatible, 3-Wire Serial

Interface

♦ Pin-Programmable Shutdown Mode and Power-

Up Reset (0 or Midscale Output Voltage)

♦ Buffered Output Capable of Driving 5kΩ 100pF

or 4–20mA Loads

♦ Space-Saving 16-Pin QSOP Package

♦ Pin-Compatible 13-Bit Upgrades Available

The serial interface is compatible with SPI™, QSPI™, and

MICROWIRE™, which makes the MAX5122/MAX5123

suitable for cascading multiple devices. Each DAC has

a double-buffered input organized as an input register

followed by a DAC register. A 16-bit shift register loads

data into the input register. The DAC register may be

updated independently or simultaneously with the input

(MAX5132/MAX5133)

♦ Pin-Compatible 14-Bit Upgrades Available

(MAX5171/MAX5173)

Both devices are available in a 16-pin QSOP package

and are specified for the extended-industrial (-40°C to

+85°C) operating temperature range. For pin-compatible

14-bit upgrades, see the MAX5171/MAX5173 data sheet;

for the pin-compatible 13-bit version, see the MAX5132/

MAX5133 data sheet.
