... A/D converters. Included are seven seg- 2 ment decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal dis- play (LCD) and includes a multiplexed backplane drive; the ICL7107 will directly drive an instrument size light emitting diode (LED) display. The ICL7106 and ICL7107 bring together a combination of high accuracy, versatility, and true economy ...

... ICL7106, ICL7107, ICL7106S, ICL7107S Detailed Description Analog Section Figure 3 shows the Analog Section for the ICL7106 and ICL7107. Each measurement cycle is divided into three phases. They are (1) auto-zero (A-Z), (2) signal integrate (INT) and (3) de-integrate (DE). Auto-Zero Phase During auto-zero three things happen. First, input high and low are disconnected from the pins and internally shorted to analog COMMON ...

... Also the P-P FIGURE 4. USING AN EXTERNAL REFERENCE TEST The TEST pin serves two functions. On the ICL7106 it is coupled to the internally generated digital supply through a 500 resistor. Thus it can be used as the negative supply for externally generated segment drivers such as decimal points or any other presentation the user may want to include on the LCD display ...

... ON. In all cases negligible DC voltage exists across the segments. TO LCD DECIMAL Figure 8 is the Digital Section of the ICL7107 identical POINTS to the ICL7106 except that the regulated supply and back plane drive have been eliminated and the segment drive has been increased from 2mA to 8mA, typical for instrument size common anode LED displays ...

... In the ICL7106 or the ICL7107, when the analog COMMON is used as a reference, a nominal +2V full- scale integrator swing is fine. For the ICL7107 with +5V supplies and analog COMMON tied to supply ground, a 3.5V to +4V swing is nominal. For three readings/second (48kHz clock) nominal values for C 0 ...
