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.
The serial digital interface is SPI compatible and is easily
interfaced to popular FPGAs and microcontrollers. Power
consumption is limited to 11mW at a sampling rate of 125kSPS,
and an operating current of just 8µA typical between
conversions, when configured for Auto Powerdown mode.
The ISL26310/11/12/13/14/15/19 feature up to 5kV Human
Body Model ESD survivability and are available in the popular
SOIC and TSSOP packages. Performance is specified for
operation over the full industrial temperature range (-40°C to
+125°C).
