OE
4-2
4.1
OE
The OE pin is used for enabling the outputs of the ADC. The outputs are
enabled with jumper LNK3 removed and are in 3-state configuration with the
jumper link installed.
4.2
EXTREF
The EXTREF pin is used for selecting the internal or external reference to be
used by the ADC. With jumper LINK4 removed, the device will operate using
the internal reference source. With jumper LNK4 installed, the ADC will use
the external reference voltages applied to pins REFT and REFB.
4.3
CON0 and CON1
The ADC has two mode pins, configuration Input 0 (CON0) and configuration
input 1 (CON1). These control the input range and input configuration, i.e.,
differential or single ended input mode, of input pins VINP and VINM.
Changing the gain of the on-chip PGA (programmable gain amplifier) controls
the input range. The ADC mode of operation can be changed using jumper
links LNK2 and LNK5 according to Table 4–1 and Figure 4–1.
