ICL7136CPLZ

The ICL7136CPLZ is a 3-1/2 digit LCD low power display A/D Converter with over range recovery. Included are seven segment decoders, display drivers, a reference and a clock. The ICL7136 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive. The ICL7136 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 (maximum) 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.

• First reading over range recovery in one conversion period
• Guaranteed zero reading for 0V input on all scales
• True polarity at zero for precise null detection
• 1pA Typical input current
• True differential input and reference, direct display drive
• Low noise (<lt/>15µVP-P)
• On chip clock and reference
• No additional active circuits required
• Low power, less than 1mW
