12-bit SAR
Easy to Use, Cost
Effective SAR ADCs
with 1, 2, 4, and
8-channel Inputs
The new ISL263xx family of multichannel-
input SAR ADCs from Intersil offer a new
level of cost-effectiveness and ease of use
for all types of Industrial Process Control,
Instrumentation, and related measurement
applications. Input buffers that simplify input
drive requirements and pin—compatibility
across the entire product family make the
family easy to design, and re-use across
multiple platforms and product families.
