Part Number: ADS1263 Other Parts Discussed in Thread: OPA337 Hi
I intend to supply the ADS1263 using 5V.
Also, the sensor to be read will be used with an charger amplifier (OPA337), with T-network configuration (as in the image below) and also supplied…
Just to confirm, can I connect the output of an op-amp (OPA336 or OPA337) directly to the Comp pin of the UC3845? Is there no need for an open-collector or drain circuit? I noticed that there is a current source in parallel with the UC's error amplifier…
Part Number: OPA337 I am setting up an amplifier for a piezoelectric acoustic sensor (frequency response 50Hz to 20kHz).
The sensor has very high output impedance.
High input impedance and low noise is required for the op-amp.
I have several questions…
I'm running ORCAD v16.3.
I set the simulation up in accordance to the following recommendation from the model, itself:
* ADD .OPTIONS ITL=40 AND .OPTIONS GMIN=10p TO NET LIST IF SIMULATION DOES NOT * CONVERGE
I get the following statements in the output…
Part Number: ADS1299 Other Parts Discussed in Thread: ADS1263 , 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 and…
Part Number: PCM1681 Other Parts Discussed in Thread: OPA2353 , OPA337 , OPA2134 , OPA1622 I have several questions about PCM1681. Please refer to the datasheet, figure 26 and figure 33 show the recommended active filter circuits, my question is: (1): can…
Hi Daniel,
Thank you for your support.
In fact, your point about high voltage is right and we do need a charge amplifier for our application. We need charge amplifiers that can convert charges from range 450 pico Columbs to 10 micro Columbs to voltage…
Hi Kai,
Thanks a lot for your quick reply.
The supply voltage is 5V.
The input signal amplitude is around 5mV.
The input signals are AC coupled.
I also tried OPA337. But it did not work.
Best, Hai
Matthew,
OPA337 is a low voltage amplifier with the maximum supply voltage of +/-2.75V so you may not power it using +/-15V supplies.
You cannot pick the value of the feedback resistor based solely on the desired RC time constant because as Miriam mentioned…
