MAX136 Datasheet | Maxim Integrated

Low Power, 31⁄2 Digit A/D Converter with Display Hold General Description The MAX136 is a monolithic analog-to-digital converter (ADC) with very high input impedance. It differs from the Maxim ICL7136 in that the MAX136 provides a Hold pin, which makes it possible to hold or "freeze" a reading. The MAX136 directly drives a nonmultiplexed liquid crystal (LCD) display, requiring no external drive circuitry. With minor external ponent changes, it is pin patible with the ICL7116 but with significantly reduced power consumption, making the MAX136 a superior device for portable systems. Versatility and accuracy are inherent Features of this ADC. The dual-slope conversion technique...
