16 and 20-Bit Voltage DACs
General Description
The MAX5717 and MAX5719 are serial-input, unbuffered
16 and 20-bit voltage-output unipolar digital-to-analog
converters (DACs) with integrated feedback resistors
that allow bipolar operation when used with an external
operational amplifier. These DACs provide low glitch
energy, low noise, tight bipolar resistor matching, and high
accuracy. The DACs feature ±4LSB INL (max, 16-bit) over
the temperature range of -40°C to +105°C. Integrated
precision setting resistors make the DACs easy to use.
The MAX5717 and MAX5719 feature a 50MHz, 3-wire
SPI™, QSPI™, MICROWIRE™, and DSP-compatible
serial interface.
On power-up, the output resets to zero-scale, providing
additional safety for applications which drive valves or
other transducers that need to be off on power-up. The
DAC output settles in 750ns and has a low offset and
gain drift of ±0.1 ppm/°C of FSR.
The MAX5717 is functionally similar to the MAX542,
but with significantly faster settling time. The MAX5719
provides a similar speed improvement as well as an
increase in resolution to 20 bits.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation 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.
