AD592BNZ Datasheet PDF - ADI

●The AD592 series 2-terminal monolithic Temperature Transducer provides an output current proportional to absolute temperature. For a wide range of supply voltages the transducer acts as a high impedance temperature dependent current source of 1µA/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. With a single supply (4 to 30V) the AD592 is 0.5°C temperature measurement accuracy. A wide operating temperature range (-25 to +105°C) and highly linear output make the AD592 an ideal substitute for older, more limited sensor technologies (i.e., thermistors, RTDs, diodes, thermocouples). As 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. The high output impedance of the AD592 provides greater than 0.5°C/V rejection of supply voltage drift and ripple.
