The TC1047 and TC1047A can accurately measure temperature from -40°C to +125°C. With the TC1047, the supply voltage can vary between 2.7V and 4.4V. The power supply range of the TC1047A is from 2.5V to 5.5V. The output voltage range for these devices is typically 100 mV at -40°C, 500 mV at 0°C, 750 mV at +25°C and 1.75V at +125°C. A 10 mV/°C voltage slope output response allows for a predictable temperature measurement over a wide temperature range. The TC1047 and TC1047A are packaged in 3-pin SOT-23B packages, making them ideal for space-critical applications. Package Type TC1047A VDD = 2.5V to 5.5V VDD PIC® A/D VSS Microcontroller Converter Note: 3-Pin SOT-23B is equivalent to JEDEC TO-236
