Description: CL7106CPL, ICL7107CPLAnalogue to DigitalConverter/Display Drivers  These two ICs are high performance, low power 31/2 digit A/D converters. The input requires about 1pA typically. Other features are guaranteed zero reading for 0 volts input on all scales; true polarity at zero for precise null detection; true differential input and reference; low-noise; on chip clock and reference; low supply current 0· 8mA typical. The output of the 7106 will drive LCD displays directly and a +9V supply is required at pin 1 and ground at pin 26. This IC is ideally suited for battery operation since it requires only 0· 8mA supply current. The output of the 7107 will drive LED displays directly and a +5V supply is required at pin 1, -5V at pin 26 and ground at pin 21. Accuracy ▒1 count in ▒2000 counts guaranteed.  Display Driver and Thermometer PCB  A printed circuit board is available for use with the 7106 or 7107. The same printed circuit may be used to produce a ▒1· 999V (2V) voltmeter, a ▒0· 1999  (200mV) voltmeter or a thermometer using the LM35CZ or LM35DZ ICs, with either an LED or LCD. A leaflet is supplied with every PCB, which shows how to build and calibrate the projects.  7106 7106 7107 7107  2V LCD 200mV 2V LED 200mV  LCD 180  R1 Min Res 15k 22k 15k 22k  R2 Min Res 470k 47k 470k 47k  R3 Min Res 100k 100k 100k 100k  R4 18-turn Cermet 10k 1k 10k 1k  R5 Min Res 1M 1M 1M 1M  R6 Min Res - - 150  C1 Poly Layer 0· 1╡F 0· 1╡F 0· 1╡F 0· 1╡F  C2 Poly Layer 0· 047╡F 0· 47╡F 0· 047╡F 0· 47╡F  C3 Poly Layer 0· 22╡F 0· 22╡F 0· 22╡F 0· 22╡F  C4 Ceramic 100pF 100pF 100pF 100pF  C5 Poly Layer 0· 01╡F 0· 01╡F 0· 01╡F 0· 01╡F  IC1 7106 7106 7107 7107  Link L1 Yes Yes Yes Yes  DIL Socket 40-pin 1 1 1 1  PCB (BY76H) 1 1 1 1  Display - 1 needed PF51 PF51 BY66W BY66W  Display - 1 needed - - BY67X BY67X
