TYPICAL APPLICATIO
LTC2401/LTC2402
Figure 35 shows the block diagram of a demo circuit
(contact LTC for a demonstration) of a multichannel
isolated temperature measurement system. This circuit
decodes an address to select which LTC2402 receives a
32-bit burst of SCK signal. All devices independently

convert either the thermal couple output or the thermistor
cold juntion output. After each conversion, the devices
enter their sleep state and wait for the SCK signal before
clocking out data and beginning the next conversion.
