16-Bit, Parallel-Input, Voltage-Output DACs
with Internal Reference
General Description
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
between +2V and AV_DD. TheMAX5650/MAX5651/
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
voltage output ranges from 0 to V_REF.
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.
