MAX5215/MAX5217

14-/16-Bit, Low-Power, Buffered Output,

Rail-to-Rail DACs with I²C Interface

General Description

Features

The MAX5215/MAX5217 are pin-compatible 14-bit

and 16-bit digital-to-analog converters (DACs). The

MAX5215/MAX5217 are single-channel, low-powered,

buffered voltage-output DACs. The devices use a preci-

sion external reference applied through the high resis-

tance input for rail-to-rail operation and low system power

consumption. The MAX5215/MAX5217 accept a wide

2.7V to 5.5V supply voltage range. Power consumption

is extremely low to accommodate most low-power and

low-voltage applications.

The MAX5215/MAX5217 have an I²C-compatible, 2-wire

serial interface that operates at clock rates up to 400kHz.

On power-up, the MAX5215/MAX5217 reset the DAC out-

put to zero, providing additional safety for applications

that drive valves or other transducers that need to be off

on power-up. The DAC output is buffered resulting in a

low supply current of 80µA (max) and a low offset error

of 0.25mV. An asynchronous active-low input, AUX,

is provided. This input can be programmed to support

clear or load DAC operations, independent of the serial

interface. The MAX5215/MAX5217 are available in an

ultra-small (3mm x 5mm), 8-pin µMAXMpackage and are

specified over the -40°C to +105°C extended industrial

temperature range.
