Other Parts Discussed in Thread: OPA2357 , LMP7712 I'm using the OPA2357 configured as a precision rectifier as part of a peak detector circuit. To save power the op-amp is disabled until the input signal passes a 100mV threshold, at which point a comparator…
Hi Emanuel,
I see you have removed the AC coupling capacitor from the input path. As your input signal is centered around 0V, this will cause the input to the PGA to go below the common-mode input range. Also, you are attenuating the input source much…
Part Number: TDC1000 Other Parts Discussed in Thread: OPA2357 , LM2733 If I wanted to boost the signal from the TDC1000 to increase the signal (lets say a 5X increase) to get better sensing distance, is the OPA2357 amplifier a good choice? Is there a specific…
Hello Vishy,
Thank you for your suggestion and prompt response.
OPA2357 has very low supply voltage and I want to use amplifier for ultrasonic sensor which is used for non-intrusive and non-invasive type of water flow measurement application.
For this…
Other Parts Discussed in Thread: THS4520 , ADS58C28 , LMH6552 , THS4509 , THS4541 , OPA2357 Hi all, Would you mind if we ask THS4520? Our customer will use ADS58C28, and our customer would like to measure followings signal; <Sampling signal> -Input voltage…
TDC1000 allows transmitting a pulse (cycle) 180 degree out of phase, please see page 23 of TDC1000 datasheet . For your case you would need to place an inverting buffer on TX2 line externally (try opa2357 or similar amps).
Cheng,
Below are my comments about your approach.
1. Due to large attenuation of ultrasonic signal in the air it may be needed to drive the transducer with higher voltage. TDC1000 operating range is 2.7 to 5.5V and you may want to connect the VDD to a 5V …
Other Parts Discussed in Thread: OPA357 , OPA2357 Hi All,
I would like to ask one question about OPA357 AIDBVT footprint.
I downloaded PADS-PowerPCB footprint from http://focus.ti.com/docs/prod/folders/print/opa357.html , and measured the…

I have a voltage signal in the range of 10 µV which should be amplified…
Other Parts Discussed in Thread: ADS804 , OPA2357 DearSir.
Attached a schmetics of ADS804 8585.SCHEMATIC1 _ CHANNEL1.pdf
I must have go wrong , It looks like that the pins REFT,REFB are output .
I have used them as inputs.
What I need is to convert…
