To learn more about SAR ADC, i suggest going through T I Precision Labs: Basic Operation of SAR and Delta Sigma ~click here~ , it is a video series covering this and other topics, the power point is also available.
Overall, to complete one conversion, the…
Hi Sunney,
Before I get to answering your questions I just want to let you know that the input capacitance is actually built into the model for the OPA171!
Your simulation circuit was close but not quite right on how to properly break the circuit. Any…
Part Number: OPA2171 Other Parts Discussed in Thread: OPA4171 , , OPA4991 , OPA2991 , OPA2990 , OPA171 Hi Team,
We have received this inquiry from our customer,
I have been using this opamp as well as opa2171 and opa4171 as it was advised by a member of your…
Hi Jimmy,
Both of these designs do not implement a complete todays AC Charger.
TIDA-00637 covers most of the system blocks for an AC Charger:
-Pilot signal generation but OPA171 must be replaced by TLV1805 to comply to newer requirements -GFCI with self…
Hi Kai,
Thank you for answer but I tried my circuit with opa171 and it works. opa187 and opa171 are rail to rail op amp and has same CMRR. Why opa187 does not work like opa171 ?. I can not understand this.
Hello Kevin,
As you stated correctly, the duty cycle indicates the maximum charging current, the EVES can provide to the EV. This maximum current is dependent on the hardware within the EVSE and the grid capabilities. This means once the EVSE is installed…
Part Number: OPA170 Other Parts Discussed in Thread: TLV341 , OPA171 , OPA990 Hi, Staff
Customers are currently using OPA170 SOT-5X3 (DRL Package). We are planning to revise the application, but we will not change the board layout.
Customer demands are looking…
Part Number: OPA4172 Other Parts Discussed in Thread: OPA172 , OPA2991 , OPA171 , OPA2172
Hi all,
The customer wants to replace OP275 by our OPA4172.
But the customers are worried about the effect of difference of the voltage gain in this audio application…
Hi Eggsy,
I just realized that the input signal does not have a 50% duty cycle, like I was using in simulation. The device might not have enough bandwidth to respond to the input signal. Even with the OPA171 the waveform is barely getting to the peak…
