The MAX5650/MAX5651/MAX5652 parallel-input, volt-

age-output, 16-bit, digital-to-analog converters (DACs)

provide monotonic 16-bit output voltage over the full

extended operating temperature range. The MAX5650/

MAX5651 include an internal precision low drift

(10ppm/°C) bandgap voltage reference, while the

MAX5652 requires an external reference. The MAX5650

operates from a +5V single supply and has a +4.096V

internal reference. The MAX5651 operates from either a

+3V or +5V single supply and has a +2.048V internal

reference. The MAX5652 operates from either a +3V or

+5V single supply and accepts an input reference voltage

MAX5652 parallel inputs are double buffered and con-

figurable as a single 16-bit wide input or a 2-byte input.

The MAX5650/MAX5651/MAX5652 unbuffered DAC

The MAX5650/MAX5651/MAX5652 feature an active-low

hardware clear input (CLR) that clears the registers and

the output to zero-scale (0000 hex) or midscale (8000

hex), depending on the state of the MID/ZERO input.

These devices include matched scaling resistors for use

with a precision external op amp (such as the MAX400)

to generate a bipolar output-voltage swing.

The MAX5650/MAX5651/MAX5652 are available in a 32-

pin, 5mm x 5mm TQFN package and are guaranteed

over the extended temperature range (-40°C to +85°C).

For 14-bit, pin-compatible versions of the MAX5650/

MAX5651/MAX5652, refer to the MAX5653/MAX5654/

MAX5655 datasheet.

For 12-bit, pin-compatible versions of the MAX5650/

MAX5651/MAX5652, refer to the MAX5656/MAX5657/

MAX5658 datasheet.
