I am working with two sensors with 4 pin as output. My question is simple: I want to make circuit that allows me to short circuit the output of either one of the sensors individually when needed. I am considering using quad 1:2 demux (AGD774a) and shorting either the pins on channel B together while measuring with channel A and vice versa. So when I want the channel for normal measurement I will use channel A and when I want output of sensor shorted I change the channel of the switch. So, my main question is whether using a demux to solve the requirement is a wise choice or there is some other way it can be achieved. Notes: The sensor is an ultrasonic transducer which produces only millivolt level outputs. In use the sensor is placed in a heating chamber to increase its temperature. When the temperature of the transducer is varied, it produces spurious temperature-change related voltages. After heating we need to short the output pins to release all the residual voltage. The charge itself is small. May be I can do a worst case calculations and attach a resistance as well with it. Temperature Sensors, Transducers Temperature Sensors, Transducers are in stock at Kynix Electronics. Kynix offers inventory, pricing, & datasheets for Temperature Sensors, Transducers. To know more, please view our large section of Temperature Sensors, Transducers below. The voltage drop is small - in the mV range. I do not think that an electromechanical relay is required. The sensor will not be connected to Micro-Controller. Shorting is needed to discharge the piezo in the sensor which occurs when the temperature is changed.
