6 / 13 page GND VOUT VDD Thermal Diodes 6 TMP235, TMP236 SBOS857 – SEPTEMBER 2017 www.ti.com Product Folder Links: TMP235 TMP236 Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated 7 Detailed Description 7.1 Overview The TMP23x devices are a family of linear analog temperature sensors with a output voltage proportional to temperature. These temperature sensors have an accuracy from 0°C to 70°C of ±1°C (TMP23x) and ±2°C (TMP23x). The TMP235 device provides a positive slope output of 10 mV/°C over the full –40°C to +150°C temperature range and a 2.3 V to 5.5 V supply range. The higher gain TMP236 sensor provides a positive slope output of 19.5 mV/°C from –10°C to +125°C and a 3.1 V to 5.5 V supply range. A class-AB output driver provides a maximum output of 100 µA to drive capacitive loads up to 1000 pF. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 TMP23x Transfer Function Table 1 lists the output voltages of the TMP23x devices across the full operating temperature range. The first- order columns of this table are the straight line references that determine the accuracy specifications of the TMP23x devices (see Electrical Characteristics). The second-order columns show the small amount of typical nonlinearity in the output. Table 1.
