16-Bit, Parallel-Input, Voltage-Output DACs
with Internal Reference
General Description
Features
♦ 16-Bit Resolution
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
♦ Parallel 16-Bit or 2-Byte Double Buffered Interface
♦ Guaranteed Monotonic
♦ Maximum INL: ±± LꢀB
♦ Fast 2µs ꢀettling Time
♦ Clear Input (CLR) ꢀets Output to Zero-ꢀcale or
Midscale
♦ Integrated Precision Resistors for Bipolar
Operation
♦ Integrated Precision Bandgap Reference:

between +2V and AV . TheMAX5650/MAX5651/
DD
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
+2.0±8V (MAX5651)
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.
