Microprocessor-Compatible,
14-Bit DACs
_______________________________________________________________________________________ 5
__________Pin Description (MX7534)
NAME FUNCTION
1
REF Reference Input to DAC
2 RFB
PIN
3 IOUT Current Output
4 AGNDS
Analog Ground Sense. Reference
point for external circuitry. AGNDS
should carry minimum current.
8 D6 Data Bit 6
7 D7 Data Bit 7
6 DGND Digital Ground
5 AGNDF
Analog Ground Force. Carries current
from internal analog ground connec-
tions. AGNDS and AGNDF are tied
together internally.
Feedback Resistor. Used to close the
loop around an external op amp.
