> The other interesting chip is the TSL23x series of light to frequency >converters. I do not have an appropriate data book so the question is >what is the difference between the TSL230 and TSL235? What TI book contains this information? The 235 is a fixed output version of the 230. The 230 is pin programmable for output frequency scaling and light sensitivity. The 235 is 3 lead 230 device with the sensitivity and output scaling preset by TI. Vcc, Gnd, and Fout about 10Hz to 500kHz 50% duty square wave. All of TI optic sensors are described in the TI Intelligent Optic Sensor databook. I don't have the Book # with me but I cat get it at work if you need it. TI's web site also contains the information. -- Richard A. Smith "I don't believe in magic, but I can simulate it." spam_OUTras2TakeThisOuTtant.com - Phil Kinkade
