ICL7107CM44Z Datasheet PDF - Intersil

●The ICL7107CM44Z is a high performance low power 3-1/2-digit Analog-to-digital Converter (ADC) designed to interface with a liquid crystal display and includes a multiplexed backplane drive, the converter will directly drive an instrument size light emitting diode display. It brings together a combination of high accuracy, versatility and true economy. It features auto zero to less than 10µV, zero drift of less than 1µV/°C, input bias current of 10pA and rollover error of less than one count. True differential inputs and reference are useful in all systems, but give the designer an uncommon advantage when measuring load cells, strain gauges and other bridge type transducers. Finally, the true economy of single power supply operation enables a high performance panel meter to be built with the addition of only 10 passive components and a display.
