CMOS analog multiplexers can also be used to switch AD590
current. Due to the AD590’s current mode, the resistance of
such switches is unimportant as long as 4 V is maintained
across the transducer. Figure 24 shows a circuit that combines
the principle demonstrated in Figure 23 with an 8-channel
CMOS multiplexer. The resulting circuit can select 1 to 80
sensors over only 18 wires with a 7-bit binary word.
The inhibit input on the multiplexer turns all sensors off for
minimum dissipation while idling.
Figure 25 demonstrates a method of multiplexing the AD590 in
and their associated resistors can be added to multiplex up to
eight channels of ±0.5°C absolute accuracy over the temperature
range of 55°C to +125°C. The high temperature restriction of
125°C is due to the output range of the op amps; output to 150°C
can be achieved by using a 20 V supply for the op amp.
