PRODUCT DESCRIPTION  
are available at the package pins so that the circuit can be  
recalibrated for the thermocouple types by the addition of two  
or three resistors. These terminals also allow more precise cali-  
bration for both thermocouple and thermometer applications.  
The AD594/AD595 is a complete instrumentation amplifier and  
thermocouple cold junction compensator on a monolithic chip.  
It combines an ice point reference with a precalibrated amplifier  
to produce a high level (10 mV/°C) output directly from a ther-  
mocouple signal. Pin-strapping options allow it to be used as a  
linear amplifier-compensator or as a switched output setpoint  
controller using either fixed or remote setpoint control. It can  
be used to amplify its compensation voltage directly, thereby  
converting it to a stand-alone Celsius transducer with a low  
impedance voltage output.  
The AD594/AD595 is available in two performance grades. The  
C and the A versions have calibration accuracies of ±1°C and  
±3°C, respectively. Both are designed to be used from 0°C to  
+50°C, and are available in 14-pin, hermetically sealed, side-  
brazed ceramic DIPs as well as low cost cerdip packages.  
PRODUCT HIGHLIGHTS  
The AD594/AD595 includes a thermocouple failure alarm that  
indicates if one or both thermocouple leads become open. The  
alarm output has a flexible format which includes TTL drive  
capability.  
1. The AD594/AD595 provides cold junction compensation,  
amplification, and an output buffer in a single IC package.  
2. Compensation, zero, and scale factor are all precalibrated by  
laser wafer trimming (LWT) of each IC chip.  
The AD594/AD595 can be powered from a single ended supply  
(including +5 V) and by including a negative supply, tempera-  
tures below 0°C can be measured. To minimize self-heating, an  
unloaded AD594/AD595 will typically operate with a total sup-  
ply current 160 µA, but is also capable of delivering in excess of  
±5 mA to a load.  
3. Flexible pinout provides for operation as a setpoint control-  
ler or a stand-alone temperature transducer calibrated in  
degrees Celsius.  
4. Operation at remote application sites is facilitated by low  
quiescent current and a wide supply voltage range +5 V to  
dual supplies spanning 30 V.  
The AD594 is precalibrated by laser wafer trimming to match  
the characteristic of type J (iron-constantan) thermocouples and  
the AD595 is laser trimmed for type K (chromel-alumel) inputs.  
The temperature transducer voltages and gain control resistors  
5. Differential input rejects common-mode noise voltage on the  
thermocouple leads.
