DEscriptION
The SW7106 are high performance, low power 3%2 Digit A/D Converter. All the necessary active devices are contained in a single CMOS IC, including seven-segment decoder, display driver, voltage reference and clock. SW7106 is designed to interface with a liquid crystal display (LCD). The SW7106 bring the combination of high accuracy, versatility and economy. High accuracy, like auto-zero to less than 100μV for 2.00V full-scale measurement, or 10uV for 200.0mV full-scale measurement, input bias current of 10pA max, and rollover of less than one count. The versatility of true differential high impedance inputs and voltage reference is useful in systems, such as strain gauges or bridge-type transducers. The built in auto-zerofeature automatically correct the system offset without any external adjustments.
