JAJSKJ5F November 2020 – July 2024 TMUX7219
PRODUCTION DATA
The TMUX7219 can operate without any external components except for the supply decoupling capacitors. All inputs passing through the switch must fall within the recommended operating conditions of the TMUX7219, including signal range and continuous current. For this design with a positive supply of 15 V on VDD and negative supply of −15 V on VSS, the signal range can be −15 V to +15 V and the maximum continuous current can be up to 440 mA, as shown in the Recommended Operating Conditions, for a wide-range current measurement. The TMUX7219 device is a bidirectional, single-pole double-throw (SPDT) switch that offers low on-resistance, low leakage, and low power. These features make this device suitable for portable and power sensitive applications such as ultrasonic gas metering systems. For a more detailed analysis of the ultrasonic flow transmitter system, refer to the reference design.
