Part Number: DDC114 Hi team,
My customer is using DDC114 for PHOTODIODE SENSORS current, they use below equation to calculate the actual input current, but with this equation and same integration time, they will get different calculation result when they…
Part Number: DDC114 Hello，
One customer used DDC114 for his application, he found that when DDC114 is inactive, the data is stable, and the larger the current, the greater the data fluctuation
Could you please help to analyze?
Best regards

Part Number: DDC114 Tool/software: Hi,
the DDC114 allows to measure small down to very small currents with positive sign
(current flowing into in1..4 pin).
Now, I need a device with same/similar current measurement range where the current direction…
Part Number: DDC114 Other Parts Discussed in Thread: DDC264 I am currently investigating a problem with DDC114, where the ADC value is gradually changing with time, as shown below. Moreover, the extent of this drift differs among different boards. Is…
Part Number: DDC114 Hello,
My customer tested the DDC114's test mode operation, but it only outputs all F value, not the expected 0 output.
The captured images of the PINs they measured are shown below.

Part Number: DDC114 Hi,
When Test Mode is used, what is the default output value?
My customer is testing the DDC114 on custom board.
In test mode, the output value of all input ranges is 0xFFFFF.
Please let me know how to debug and what could be causing…
Part Number: DDC114 Good day,
In our equipment, we are using DDC114 ADC. Currently, we are trying to minimize the noise and improve the long-term stability of data acquisition.
For reference voltage generation we have been using the recommended circuit…
Hi Beak,
Thanks for the latest information on the excel file.
Sorry if I misinterpret the data you have in the original excel file. To make sure I understand your dataset correctly, the plot on the left is the A-side data, and the plot on the right is…
Part Number: DDC114 We are trying to run the DDC114 in cont mode. After the chip is taken out of reset we begin cont mode as shown. From top to bottom: data valid, reset, conv, dclk. After approximately 200-300 ms after the reset goes high, we leave cont…
Part Number: DDC114 We have written a driver for the DDC114 and want to tune range & integration time in order to maximise signal to noise ratio. Our photodiode expected current output range is 1pa to 100nA. Using a linear power supply set for 1 volt…
