The ICL7106 and ICL7107 are high performance, low power, 31/2 digit A/D converters. They combine high accuracy, versatility, and true economy. Features include auto-zero, low zero drift, low input bias current, and low rollover error. They are useful in all systems and provide an uncommon advantage when measuring load cells, strain gauges, and other bridge type transducers. Single power supply operation enables the construction of a high performance panel meter with minimal additional components.
The document describes the Intersil ICL7106 and ICL7107 families of analog-to-digital (A/D) converters. These devices are designed as high performance, low power solutions that integrate seven-segment decoders, display drivers, a reference voltage source, and an on-chip clock. The ICL7106 is specifically configured to interface with liquid crystal displays (LCD), while the ICL7107 drives light emitting diode (LED) displays directly.
