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…
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…
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 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…
