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.
