I am designing a transimpedance amplifer to run at 10mA in 100uS to detect proximity of an object (low power application)
I am intending to use the VSMB1940ITX01 IR LED and the VEMD6110X01 IR photodiode.
I am looking at using the standard transimpedance amplifier in either passive or active configuration. The output current when illuminated is in the uA range but what determines the max voltage I can get from this in choosing my load resistor?
Also does using an active over a passive configuration help? I've had a look at multiple application notes but to little avail.
Any help greatly appreciated!
