A_D_converter

Published:2009/7/20 3:54:00 Author:Jessie

A/D converter.The circuit shown is an 8-bit binary A/D converter when using the 8240 or a 2-digit BCD A/D converter when using the 8250.The input strobe first resets then triggers the 8240/8250 and set the flip-flop,which enables the counter. The stair case from the op amp counts down until reaches the analog input, at which time the comparator resets the flip-flop and stops the count,The digital word at the eight outputs is the complementary binary or BCD equivalent of the analog input.As shown the maximum conversion time is 2.6 ms,determined by R and c at pin 14 of the counter.The not-Q output of the flip-flop is convenient to use as a data ready flag since it is high when conversion is complete(courtesy Intersil, Inc.).   (View)

Celsius_temperature_to_frequency_converter

Published:2009/7/20 3:52:00 Author:Jessie

Celsius (Fahrenheit) temperature-to-frequency converter. No sensor is required since the AD537 has an internal VTEMP output. The converter output tracks the temperature at a rate of 10 hertz per degree Celsius or Fahrenheit, depending on the resistor-capacitor values chosen. All values in parentheses are for Fahrenheit. To calibrate measure the room temperature in Kelvin. Measure the temperature output at pin 6 at that temperature. Calculate the offset adjustment by dividing the VTEMP at pin 6 in milli volts by the room temperature in Kelvin, then multiplying by 273.2 The offset voltage will be in milli volts. Then disconnect the 49-ohm resistor and adjust the 2K pot for the offset voltage at pin 7. Connect the 49dm resistor. Then adjust the 500-ohm slope trimmer for room temperature, or 25℃, which results in 250 hertz (courtesy Analog Devices, Inc.).   (View)
