Hi Phuc,
as I already mentioned, application note "sloa033" contains some mistakes and deserves a revision…
Part Number: TLV2771 hi
There is the question. In this document, http://www.ti.com/lit/an/sloa033a/sloa033a.pdf , I cannot tell the difference between voltage mode and charge mode. Why we can only consider Cf on charge mode and ignore Cp and Cc?
Part Number: TLV2771 Hello,
I am trying to use the charge amplification circuit from TI (link:- https://www.ti.com/lit/an/sloa033a/sloa033a.pdf page-4 ) for my sensor ( https://www.mouser.com/ProductDetail/824-1-1000288-0 ). The problem is sometimes the…
Part Number: TLV2771 So, I got this circuit, my sensor is a piezoceramic disk and I use small round ball of steel to impact the piezo.
The problem is when i connect the OpAmp the signal is offset and this offset increase with multiple impact.
I just dont…
Part Number: ADS1299 Other Parts Discussed in Thread: ADS1263 , TEST , TLV2771 , TLV6742 , OPA337 , OPA2625 Hello!
I am working on an application using a piezoelectric sensor (disk). I have tried to use ADS1299 and ADS1263 to acquire the signal from the sensor…
Other Parts Discussed in Thread: INA326 , TLV2771 , INA327 , TPIC8101 Hi everybody,
I want to build a simple voltage amplifier circuit for a piezo-ceramic slide/sensor (sensor data see attached pdf).
The sensor is to record sound in a frequency range up to…
Part Number: TLV2771 Can some one please give me detailed derivation of higher cutoff and lower cutoff frequencies of charge mode and voltage mode amplifier given in application note sloa033a?
I have simulated both the circuits given in this app. note…
Other Parts Discussed in Thread: TLV2771 Currently I want to use TLV2771 circuit to connect to our piezoelectric material . I am not sure if it fit our demand.
Actually my major is not in this field. This is all new to me. And I saw a lot of chips in…
