perature limits in Table I are those recommended for type J and
type K thermocouples by the majority of vendors.
SINGLE AND DUAL SUPPLY CONNECTIONS
The AD594/AD595 is a completely self-contained thermocouple
conditioner. Using a single +5 V supply the interconnections
shown in Figure 1 will provide a direct output from a type J
thermocouple (AD594) or type K thermocouple (AD595) mea-
suring from 0°C to +300°C.
Any convenient supply voltage from +5 V to +30 V may be
used, with self-heating errors being minimized at lower supply
levels. In the single supply configuration the +5 V supply con-
nects to Pin 11 with the V– connection at Pin 7 strapped to
power and signal common at Pin 4. The thermocouple wire in-
puts connect to Pins 1 and 14 either directly from the measuring
point or through intervening connections of similar thermo-
couple wire type. When the alarm output at Pin 13 is not used it
should be connected to common or –V. The precalibrated feed-
back network at Pin 8 is tied to the output at Pin 9 to provide a
10 mV/°C nominal temperature transfer characteristic.
By using a wider ranging dual supply, as shown in Figure 2, the
AD594/AD595 can be interfaced to thermocouples measuring
both negative and extended positive temperatures.
