[introduction] grow continuously to the demand of segregation in 48V car application. This is the method of a kind of compact, efficient, dovish, low noise, can keep apart 48V system through CAN interface.   The to segregation demand in 48V car application increases continuously. This is the method of a kind of compact, efficient, dovish, low noise, can keep apart 48V system through CAN interface.   Be today’s car to design is behavior of a kind of balance. Satisfying increasingly…

[introduction] AD8494/AD8495/AD8496/AD8497 all is the J that uses easily model with K thermocouple amplifier. The little tension changeover that these amplifier produce thermocouple node is modulus converter (ADC) or small controller read extraction signal easily. The gain that outputs end to amplifier from thermocouple is 5 MV/°C about.   AD8494/AD8495/AD8496/AD8497 all is the J that uses easily model with K thermocouple amplifier. The little tension changeover that these amplifier produce thermocouple node is modulus converter (ADC) or small controller read…
