I'm designing my first ever circuit for a hobby project. I've a sensor
that outputs in mV and a controller with ADC. The ADC is 16 bits, VDDA =
3.0 V, Temp =25°C, fADCK = 1.0 MHz. Since the sensor voltage that is fed
is to the controller is low I'm in a predicament! Should I use a low
pass filter or a band pass filter in this application? Do you have a
circuit that I can relate to?
The sensor is a screen printed piezoelectric sensor. Since it is printed
on textile, textiles present a very low dielectric constant that reduces
the surface wave losses and increases the impedance bandwidth.
How about a low pass filter followed by LTC6085
and then to the ADC KW40Z
Any advice is appreciated. Thanks.
