T2M Analog/Codec Temperature Sensor IP Core

Temperature Sensor IP Core

Description and Features

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.

 

 

Features

•   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)

•        Temperature detection accuracy with fine trim at two accurate temperature points (e.g. 25℃ and 75℃):

±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
