Ahmed,
What sensor are you using and what is the expected current output signal?
With the large transimpedance gain (1Mohm) and large sensor capacitance of 185nF, the bandwidth will not be very wide, maybe on the order of 10kHz. You are using the…
Part Number: CC2652R Other Parts Discussed in Thread: SIMPLELINK-CC13X2-26X2-SDK Hi TI Team,
We loaded with(bim-off-chip + zrouter -ota -switch example).
using cc2652 launchpad board : 17mA
using our cc2652 custom board 24 mA
Is this normal…
I found on google, the android connection interval is 7.5ms, this should be more quick than ios.
If I add the ccservice.c/h into my project, will this infulence the ios OTA that does not contain connection control service?
Thanks!
Part Number: OPA860 Other Parts Discussed in Thread: DEM-OTA-SO-1A , TINA-TI Hello,
I've expected to use operational transconductance amplifier (OTCA) OPA860 in my design as a wideband voltage to current converter (from a standard 50 Ohm equipment,…
Hi Kai,
I attached the schematic as below.
I use the PCB of DEM-OTA-SO-1A Demonstration Fixture.
The IQADJ set 220 ohm.
I need to hold a 1V, 5ns~10ns of pulse to 5us~10us.
Can you please advise us how to implement the function with OPA860…

APD:
- Photocurrent: pulses of a few µA, width on the order of 10 ns

Hello Evan,
Good day.
A follow-up inquiry.
Is it possible to pulse width modulate the signal with circuitry on the DEM-OTA-SO? I am looking for output of a 3 ns pulse width at a 1kHz repetition rate either right before or after amplification with…
Hi Frank,
At light load or no load the regulator goes into DEM (Diode emulation mode) behavior. This helps to improve efficiency. So, the mode you're looking for is DEM. If you need low ripple at no load or light load choose an inductance with ripple…
Hi Onkar, Thanks for the response. I have updated the output capacitance to 47uf and still the IC is not regulated to 16V output? with same design. I have some points while checking schematic 1. SYNC pin is short to GND so, it working in DEM mode 2. PG1…
Part Number: LAUNCHXL-CC3235SF Other Parts Discussed in Thread: CC3235SF Tool/software: Hello,
I need help on running a successful OTA application. Here are the notes:
1. For the development purposes, i am using an unsecure connection to my server…
