ZHCSJR9A May 2019 – November 2019 AMC1035-Q1
PRODUCTION DATA.
The high input impedance of the AMC1035-Q1 is optimized for usage in voltage-sensing applications. Additionally, the internal voltage reference supports temperature sensing using a positive temperature coefficient (PTC) or a negative temperature coefficient (NTC) sensor often integrated in the IGBT module.
The same reference is internally used by the modulator, resulting in a ratiometric system solution that minimizes the overall temperature drift of the sensing path. Figure 47 shows a simplified schematic of the AMC1035-Q1 used for temperature sensing of the IGBT module. See the Application Example on the front page of this document for an application solution that requires isolating the temperature sensor.
