Product Number: ADAQ7767-1
How would one connect the ADAQ7767 in a ratiometric, single-ended application?
We want to use a piezoeletric sensor (TE 820M) in a ratiometric way where the supply voltage of the sensor is the same as the reference voltage of the ADC.
The sensor has a zero-g offset of VDD/2 and maximum full scale output of +-1.25 V.
Is this ratiometric working principle possible (and useful) with the ADAQ?
Could we connect the 5V from OUT_LDO to REF+ and to the VDD from the sensor?
We are planning to buffer the output of the sensor with the same 5V from the LDO and the connect it to IN1+.
IN1- and REF- would be grounded.
Thank you for your answers.
