8-bit A/D converter using an ADC-MC8B 16-pin DIP. Pin functions of the Datel ADC-MC8B chip are as follows: pin 1, ground; pin 2, logic select; pin 3, reset; pin 4, strobe; pin5, bit8 (LSB); pin6, bit7; pin7, bit6;pin8, +VCC; pin 9, bit 5; pin 10, bit4; pin 11, bit3; pin 12, bit2; pin 13, bit 1(MSB); pin 14, analog out; pin 15,VREF input; pin 16, VREF output. To calibrate, apply continous start commands to the start input. For the zero adjustment ground the analog input and vary the zero adjust pot until the LSB flickers between one and zero with all other inputs at logic zero. For the gain adjustment apply FS-1/2 LSB to the analog input and vary the gain adjust pot until LSB flickers between one and zero with all other bits at logic one (courtesy Datel Systems, Inc.).
