Hello
Do you know:
1. What is the maximum sensitivity wavelenght or color for a CdS LDR. Can this be paired with a red LED?
2. LDRs have a good electrical linearity - a linear resistor, not adding distortion? (the light - resistance characteristic linearity isn't imporatant for me)
I need to do a clasic simple and wide range audio AGC circuit, and LDR have a wide resistance variation range.
Thanks
