3 1/2 Digit, Low Power, Single Chip A/D Converter
The ICL7126 is a high performance, very low power 31/2-digit, A/D converter. All the necessary active devices are contained on a single CMOS IC, including seven segment decoders, display drivers, reference, and clock. The ICL7126 is designed to interface with a liquid crystal display (LCD) and includes a backplane drive. The supply current of 100µA is ideally suited for 9V battery operation.
The ICL7126 brings together an unprecedented bination of high accuracy, versatility, and true economy. It Features auto-zero to less than 10µV, zero drift of less than 1µV/o C, input bias current of 10p A maximum, and rollover error of less than one count. The versatility of true differential input and reference is useful in all systems, but gives the designer an unmon advantage when measuring load cells, strain gauges and other bridge-type transducers. And finally the true economy of single power operation allows a high performance panel meter or multi-meter to be built with the addition of only 10 passive ponents and a display.
The ICL7126 can be used as a plug-in replacement for the ICL7106 in a wide variety of applications, changing only the passive ponents.

NOTES:
1. Intersil Pb-free products employ special Pb-free material sets; molding pounds/die attach materials and 100% matte tin plate termination finish, which are Ro HS pliant and patible with both Sn Pb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020C.
2. Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing...
