... 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 ...

... THREE INVERTERS ONE INVERTER SHOWN FOR CLARITY OSC 1 Digital Section Figures 7 and 8 show the digital section for the ICL7106 and ICL7107, respectively. In the ICL7106, an internal digital ground is generated from a 6V Zener diode and a large P-Channel source follower. This supply is made stiff to absorb the relative large capacitive currents when the back plane (BP) voltage is switched ...

... ONE INVERTER SHOWN FOR CLARITY OSC 1 System Timing Figure 9 shows the clocking arrangement used in the ICL7106 and ICL7107. Two basic clocking arrangements can be used: 1. Figure 9A. An external oscillator connected to pin 40. 2. Figure 9B. An R-C oscillator using all three pins. The oscillator frequency is divided by four before it clocks the decade counters ...

... The integrating capacitor should be selected to give the maximum voltage swing that ensures tolerance buildup will not saturate the integrator swing (approximately. 0.3V from either supply). 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 ...
