AppNote "GP30 - External circuit for gas meters" is released


TDC-GP30Y is an ultrasonic flow converter (UFC) mainly for ultrasonic heat and water meters.


However, the TDC-GP30 can cooperate with external analog switches and an amplifier for operation in other ultrasonic applications like clamp-on or gas flow meters. In this so-called gas meter mode the chip uses the available GPIO pins to drive external analog switches with higher voltages. An external amplifier in the receive path can be added, too. In the following we describe such an external circuit in combination with the GP30-EVA-KIT.
