Pipelined Operation
Besides the two standard write-read-mode options,
pipelined operation can be achieved by connecting
WR to RD (Figure 6). With CS low, driving WR and RD
low initiates a conversion and concurrently reads the
result of the previous conversion.
_____________Analog Considerations
Reference
Figures 7a, 7b, and 7c show typical reference connec-
tions. The voltages at REF+ and REF- set the ADC’s
analog input range (see Figure 10). The voltage at REF-
defines the input that produces an output code of all
zeros, and the voltage at REF+ defines the input that
produces an output code of all ones.
The internal resistance from REF+ to REF- can be as
low as 1k
, and current will flow through it even when
the MAX114/MAX118 are shut down. Figure 7d shows
how an N-channel MOSFET can be connected to REF-
