Part Number: OPA615 Other Parts Discussed in Thread: DEM-OPA-MSOP-1A , TINA-TI , DEM-OPA-SO-1C I am trying to build the positive peak detector listed as figure 48 in the datasheet . I used the evaluation board and it did not work and I am wondering if…
Other Parts Discussed in Thread: DEM-OPA-SO-1A , OPA656 Hi,
I need a transimpedance amplifier to connect output voltage of AC resistors (value from 10 mohm to 1000 ohm) to PXI 4461 that has 1 MΩ || 217 pF on the inputs. The frequency of interest is…
Hello D,
1) I found in DS of OPA360 page6 ( Enable/Shutdown) section
"If the Enable pin is not connected, internal pull-up circuitry will enable the amplifier."
But it is probably better to tie it to 3.3V
- I agree, you may float it but I recommend…
Hi Shetye,
thanks for your help and reply us. about battery charge application use the LM317x series, as below
is the LM317 circuit planned by the customer correct?

Hi Thomas,
In your original post you stated you used Rin as 33Ω and Cin as 1μF . : Yes Thomas, You are correct. Initially I tested with External MOSFETs for cell balancing and observed that same results as observed with Internal Balance circuit. And…
Hello Erez,
TPS22917 has always-enabled RCB, SOT-23 package, and output slew-rate control to minimize inrush current. The ABS max of the output pin is 6V.
The way reverse current protection works in our devices is it requires a voltage drop from Vout…
Part Number: TPS62745 Our system Requirements
Vbat = 7.2V
Vout = 3.3V
Iout = 210mA
Require low EMI and High efficiency.
We have implemented buck converter circuit of TPS62745 using Figure 34 of datasheet.
Please review schematic and let…
Part Number: UCC28740 Other Parts Discussed in Thread: TIDA-00702 Tool/software: Hi,
We has a new design for the auxiliary power supply, and our spec. for below:
1. We need to auxiliary power supply output is 24V/3.3A(fully loaded);
2. The output…
Hi Sebastien,
I know it's been a while, we did not forget about this! I've been working for the past few weeks to try to get this system working. I think I have audio coming through now, but I have been having trouble getting our digital audio test…
