#84094 - Alternative ICs wanted |
Hello
Iam implementing a Temperature and humidity controller using At89c52 iam using a A/D converter at the sensor and a D/A convereter at the output At the DAC output, I am providing a simple electronic circuit to provide a 4-20ma current output using a circuit with NFET(TL032&TL034)(or some one can provide me the alternative ICs ) and TN0104 TN0106 (If any body wants the circuit i can mail to him. The algorithm iam using is a PID control algorithm. *I want to know how to implement a watchdog timer externally (or using software)or internally(I Dont want to change the microcontroller AT89C52). *I want alternatives for the above mentioned Ics which are avilable in bombay(India). I can mail the circuit and further details i have designed if you want for better clarification . with regards Suhail praise me to lord |
