ICL7107CPLZ

ICL7107CPLZ is a high performance, low power, 3½ digit A/D converter. Included are seven segment decoders, display drivers, a reference, and a clock. This device will directly drive an instrument size light emitting diode (LED) 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 (max) 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.

• Guaranteed zero reading for 0V input on all scales
• True polarity at zero for precise null detection
• 1pA typical input current
• Low noise less than 15µVP-P typical
• On-chip clock and reference
• Low power dissipation typically less than 10mW
• No additional active circuits required, enhanced display stability
• Common mode rejection ratio is 50µV/V typical
• Operating temperature range from 0°C to 70°C
• 40-lead PDIP package
