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.
