My designing now use AD7792 chip to measure the thermocouple input.
AD7792 chip have the Bias voltage generator, it sets the common-mode voltage of a channel to AVDD/2. It is useful in thermocouple applications.
And, due to special reason, now, I need Open the bias voltage -> measure the thermocouple input(with BOOST bit active, This reducesBias voltage power-up time) -> Close the bias voltage, then, repeat this process forever. The time of each this loop process is 200mS about, it means that each 1 second, bias voltage need be ON/OFF 5 times.
Could you helps to check whether it is acceptiable for AD7792? whether it will damage the chip.
