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…
Part Number: DDC114 I am trying to use the same settings in the EVK FPGA firmware as in the code executed by our micro while it is driving the DDC114, in order to check that we get the same sample value & noise. However, I am struggling to relate the…
Part Number: DDC114 Hi team,
My customer is using DDC114 for photodiode, and when measuring with a fixed range, it shifts by about 20 to 30 counts.
A photodiode connected to IN1 to IN3. IN4 is unused (open state). AVDD = 5V, VREF = 4.096V, DVDD = 3.3V…
Part Number: DDC114 Hi Team,
Good day.
We received query from customer and want to confirm if the minimum non-continuous mode integration time is 50us for this device. Because the integration time (non-continuous) found in electrical characteristics and…
Part Number: DDC114 Other Parts Discussed in Thread: DDC316 , IVC102 Hi Team,
Our customer is using DDC114 to collect 3 channel 100pA(max.) current. Before 3k sampling rate is ok. However, they want to increase the sampling rate to >=6ksps.
From our…
Part Number: DDC114 Hi Team, We have a customer that has some couple of inquiries with DDC114 that we hope you can help us out. - The customer is planing on controlling DDC114 in fNIRS circuit with a Atmega644P and wanted to ask if this has any sample C code…
Part Number: DDC114
Hi, I am currently working with a DDC114 with a custom board. I get the following value in TEST mode in RANGE 7 on channel 1. When i read the datasheet, on range 7 with 0pF detector the noise shall be 3.7 RMS noise (PPM FSR).
At 3 sigma…
Part Number: DDC114 Hello guys,
One of my customers is considering using DDC114 for their new products.
They have a question about DDC114 spec discription as the follow.
Q, DDC114 datasheet says that "±0.01% Reading ± 0.5ppm FSR, typ" and "±0.025% Reading…
