High performance temperature sensor. It generates output PTAT voltage with 3mV/℃ temperature coefficient typically. The output voltage, with 7pF maximum capacitance driving ability, can be directly used as an input channel for ADC.
This IP is also a special temperature sensor. While customers want to get higher temperature accuracy performance, they don’t need to trim it at accurate temperature point.
• Output PTAT voltage with 3mV/℃ temperature coefficient typically with 7pF maximum capacitance driving ability, can be directly used as an input channel for ADC
• Fast stable time as an input ADC channel, <1us (CL=5pF, ±0.1% sampling accuracy)
• Internal chopped PTAT generator to get high accurate output voltage without trim
• Temperature detection accuracy without trim:
±3.8℃ (temp. range: -40℃~150℃, with 2-sigma device mismatch at all “P+V” corners)
• Temperature detection accuracy with course trim at one accurate temperature point (25℃):
±2℃ (temp. range: -40℃~125℃, at all “P+V” corners)
±1.5℃ (temp. range: -40℃~100℃, at all “P+V” corners)
• Analog input power range: 2V~3.63V
• Operating junction temperature: -40°C ~ +25°C ~ +150°C
