The TSL13T light-to-voltage sensor used in one of my circuit designs is no longer manufactured. Finding a suitable integrated substitute has not been productive. So I've decided to try to replicate the chip's photodiode/op-amp circuit with separate devices. But I'm totally at sea here, having never worked with discrete photodiodes. The requirements for the photodiode are:
1. High sensitivity throughout the visible spectrum.
2. Miniature SMD package.
For the op-amp:
1. Operation from a single 5V supply.
2. Rail-to-rail output is desirable.
3. Low noise.
Anybody done anything like this before? If so, any parts/circuit recommendations?
