Nonvolatile, Quad, 8-Bit DACs with 2-Wire Serial

Interface

General Description

Features

♦ Nonvolatile Registers Initialize DACs to Stored

The MAX5115/MAX5116 quad, 8-bit, digital-to-analog

converters (DACs) feature nonvolatile registers. These

nonvolatile registers store the DAC operating modes

and output states, allowing the DACs to initialize to

specified configurations at power-up.

States

♦ +2.7V to +5.25V Single-Supply Operation

♦ Quad 8-Bit DACs with Independent High and Low

Reference Inputs

Precision on-chip output buffers swing rail-to-rail, and

provide 8µs settling time. The I²C-compatible, 2-wire

serial interface allows for a maximum clock frequency

of 400kHz.

♦ Rail-to-Rail Output Buffers

♦ Low 200µA per DAC Supply Current

♦ Power-Down Mode Reduces Supply Current to

25µA (max)

The MAX5115 has independent high and low reference

inputs allowing maximum output voltage range flexibili-

ty. The MAX5116 has single high and low reference

inputs for all DACs to minimize trace count and save

board space. The reference rails accept voltage inputs

that range from ground to the positive supply rail.

♦ 400kHz, I²C-Compatible, 2-Wire Serial Interface

♦ Asynchronous MUTE Input (MAX5116)

♦ Small 16-/20-Pin QSOP Packages

Ordering Information

The devices operate from a single +2.7V to +5.25V sup-

ply and consume 200µA per DAC. A software-controlled

power-down mode decreases supply current to less

than 25µA. A software-controlled mute mode sets each

DAC, or both DACs simultaneously, to their respective

REFL_ voltages. The MAX5116 also includes an asyn-

chronous MUTE input, that drives all DAC outputs simul-

taneously to their respective REFL_ voltages.

The MAX5115 is available in a 20-pin QSOP, and the

MAX5116 is available in a 16-pin QSOP package. Both

devices are specified for operation over the extended

(-40°C to +85°C) temperature range.
