12-bit, 125kSPS Low-power ADCs with Single-ended
and Differential Inputs and Multiple Input Channels
ISL26310, ISL26311, ISL26312,
ISL26313, ISL26314, ISL26315,
ISL26319
The ISL26310, ISL26311, ISL26312, ISL26313, ISL26314,
ISL26315 and ISL26319 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 SL26310, ISL26311, ISL26312, ISL26313,
ISL26314, ISL26315 and ISL26319 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 8A typical between conversions, when configured for
Auto Power-down mode.
The SL26310, ISL26311, ISL26312, ISL26313, ISL26314,
ISL26315, ISL26319 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)..
Features
Pin-compatible family allows easy design upgrades
