TC1047

TC1047/TC1047A Precision Temperature-to-Voltage Converter Features Supply Voltage Range: - TC1047: 2.7V to 4.4V - TC1047A: 2.5V to 5.5V Wide Temperature Measurement Range: -40oC to +125oC High Temperature Converter Accuracy: ± 2oC, Max, at 25°C Linear Temperature Slope 10mV/°C (typ.) Available in 3-Pin SOT-23B Package Very Low Supply Current: - 35µA Typical General Description The TC1047 and TC1047A are linear voltage output temperature sensors whose output voltage is directly proportional to the measured temperature. 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 100mV at -40°C, 500mV at 0°C, 750mV at +25°C, and 1.75V at +125°C. A 10mV/°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.
