PRODUCT DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD592 is a two terminal monolithic integrated circuit tem-  
perature transducer that provides an output current propor-  
tional to absolute temperature. For a wide range of supply  
voltages the transducer acts as a high impedance temperature  
dependent current source of 1 µA/K. Improved design and laser  
wafer trimming of the IC’s thin film resistors allows the AD592  
to achieve absolute accuracy levels and nonlinearity errors previ-  
ously unattainable at a comparable price.  
1. With a single supply (4 V to 30 V) the AD592 offers  
0.5°C temperature measurement accuracy.  
2. A wide operating temperature range (–25°C to +105°C)  
and highly linear output make the AD592 an ideal sub-  
stitute for older, more limited sensor technologies (i.e.,  
thermistors, RTDs, diodes, thermocouples).  
3. The AD592 is electrically rugged; supply irregularities  
and variations or reverse voltages up to 20 V will not  
damage the device.  
The AD592 can be employed in applications between –25°C  
and +105°C where conventional temperature sensors (i.e., ther-  
mistor, RTD, thermocouple, diode) are currently being used.  
The inherent low cost of a monolithic integrated circuit in a  
plastic package, combined with a low total parts count in any  
given application, make the AD592 the most cost effective tem-  
perature transducer currently available. Expensive linearization  
circuitry, precision voltage references, bridge components, resis-  
tance measuring circuitry and cold junction compensation are  
not required with the AD592.  
4. Because the AD592 is a temperature dependent current  
source, it is immune to voltage noise pickup and IR  
drops in the signal leads when used remotely.  
5. The high output impedance of the AD592 provides  
greater than 0.5°C/V rejection of supply voltage drift and  
ripple.  
6. Laser wafer trimming and temperature testing insures  
that AD592 units are easily interchangeable.  
Typical application areas include: appliance temperature sens-  
ing, automotive temperature measurement and control, HVAC  
(heating/ventilating/air conditioning) system monitoring, indus-  
trial temperature control, thermocouple cold junction compen-  
sation, board-level electronics temperature diagnostics,  
7. Initial system accuracy will not degrade significantly over  
time. The AD592 has proven long term performance  
and repeatability advantages inherent in integrated cir-  
cuit design and construction.  
temperature readout options in instrumentation, and tempera-  
ture correction circuitry for precision electronics. Particularly  
useful in remote sensing applications, the AD592 is immune to  
voltage drops and voltage noise over long lines due to its high  
impedance current output. AD592s can easily be multiplexed;  
the signal current can be switched by a CMOS multiplexer or  
the supply voltage can be enabled with a tri-state logic gate.

The AD592 is available in three performance grades: the  
AD592AN, AD592BN and AD592CN. All devices are pack-  
aged in a plastic TO-92 case rated from –45°C to +125°C. Per-  
formance is specified from –25°C to +105°C. AD592 chips are  
also available, contact the factory for details.
