The ISL26310/11/12/13/14/15/19 family of sampling SAR-type ADCs feature excellent linearity over supply and temperature variations, and offer versions with 1-, 2-, 4- and 8-channel single-ended inputs, and 1-, 2- and 4-channel differential inputs.

A proprietary input multiplexer and combination buffer amplifier reduces the input drive requirements, resulting in lower cost and reduced board space. Specified measurement accuracy is maintained with input signals up to VDD.

Members of the ISL26310/11/12/13/14/15/19 family of Low-Power ADCs offer pinout intercompatibility, differing only in the analog inputs, to support quick replication of proven layouts across multiple design platforms.
