MAX5215/MAX5217
14-/16-Bit, Low-Power, Buffered Output,
Rail-to-Rail DACs with I2C Interface
General Description
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 µMAXM package and are
specified over the -40°C to +105°C extended industrial
temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
