pin Description
Analog Inputs to the MUX (multiplexer). A channel input is selected by the address information at the DI pin,
which is loaded on the rising edge of SCLK into the address register (See Tables 2, 3, 4). The voltage applied
to these inputs should not exceed V
channel may corrupt the reading of a selected channel.
Analog input pin that is used as a pseudo ground when the analog multiplexer is single-ended.
Multiplexer Output pins. If the multiplexer is used, these pins should be connected to the A/DIN pins, directly
or through an amplifier and/of filter.
Converter Input pins. MUXOUT1 is usually tied to A/DIN1. MUXOUT2 is usually tied to A/DIN2. If external
circuitry is placed between MUXOUT1 and A/DIN1, or MUXOUT2 and A/DIN2, it may be necessary to protect
these pins against voltage overload.. The voltage at these pins should not exceed V
Figure 6).
Data Output pin. This pin is an active push/pull output when CS is low. When CS is high, this output is TRI-
STATE
on this pin. The word length and format of this result can vary (see Table 1). The word length and format are
controlled by the data shifted into the multiplexer address and mode select register (see Table 5).
