Part Number: TIPD176 Hello TI community,
I am using TIPD176 reference board with SFH213 photo diode, and flashing black and white light frame (from mobile screen) to view the output of the TIA in the oscilloscope. Unfortunately I am getting very low voltage…
Hi Luis,
Thank you for checking out my circuit.
What is the photodiode junction capacitance and required reverse voltage and/or do you have a photosensor part number?
The photodiode is Osram SFH 213 . Its capacitance is 11pF. The photodiode is soldered…
Hi Viny,
Design Step 3 shows the equation to calculate the minimum bandwidth for the amplifier used as a TIA. Also TIPD176 shows a more in depth derivation of the equation.
The circuit bandwidth will be dependent on your system and is set by R3 and C2…
Hi Pankaj,
TIPD176 - 1 MHz, Single-Supply, Photodiode Amplifier Reference Design in the "Design References" section of the document provides a derivation of the equation.
Thank you,
Tim Claycomb
Hi Jordan,
Please take a look at TIPD176 (1MHz, Single-Supply, Photodiode Amplifier Reference Design). This document should discuss most design consideration for a photodiode application.
I also recommend taking a look at our TI Precision Lab training…
Dear Mr. Pete Semig,
Greetings for a Great New Year. Two help I need from you,
1. SFH 7050 has a peak wavelength of 940 NM, Can you help us to understand if we can detect Glucose using this IC.
2. AFE4490 has a built in Transimpedence amplifier. Do u…
Johannes,
I agree with Art's recommendation for the TIPD176. Starting there is great.
I also think you might look into the DDCxxx family of products, if you want a digital output. The DDC products are designed specifically for photodiode integration…
Hi Marco,
I didn't read through the entire article, but after giving it a quick skim it looks correct. The zero in the 1/beta (noise-gain) response is a result of the parallel combination of the feedback and input resistors interacting with the diode…
