ASSEMBLY INSTRUCTIONS
CAUTION:
process that would allow direct contact with free liquids or
vapors. Entrapment of contaminants may occur, causing
performance degradation and permanent damage. Install after
not hermetically sealed. Do not subject to a solvent or water-wash
any clean/wash process aod then only spot clean by hand.
The DAC1136/1138 can be operated with an external
reference connected to pin 53 of the module. The current
drain on the external reference will be 1.125mA in bipolar
mode or O.125mA in unipolar mode (pin 46 should be left
open and not grounded when using an external reference
in the unipolar mode ). When an external reference is used, pin

Codi Semiconductor manufactures a reference module called
Ceftavoltl with a 10 volt output accurate to 0.001%. This out-
put is temperature compensated to within lppm/oC from
+15-C to +5 5-C. The Certavolt requires a power supply of
+28V dc @ 2OmA. To convert the +10 volt output of the Cert-
avolt to the +6 volt reguired by the DAC, the circuit shown
in Figure 5 is recommended,
