TMP17FSZ

The TMP17FSZ series monolithic Temperature Transducer that 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 TMP17FSZ to achieve absolute accuracy levels and nonlinearity errors. A wide operating temperature range (-40 to +105°C) and highly linear output make the TMP17FSZ an ideal substitute for older, more limited sensor technologies (i.e., thermistors, RTDs, diodes, thermocouples). As the TMP17FSZ 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 TMP17FSZ provides greater than 0.5°C/V rejection of supply voltage drift and ripple.
