12-bit, 125kSPS Low-power ADCs with Single-ended and Differential Inputs and Multiple
Input Channels
DATASHEET
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 ISL26310, 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 8µA typical between conversions,
when configured for Auto Power-down mode.
The ISL26310, 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
• Excellent differential non-linearity (0.7LSB max)
• Low THD: -86dB (typ)
• Simple SPI-compatible serial digital interface
• Low 2.2mA operating current
• Power-down current between conversions 8µA (typ)
• +5.25V to +2.7V supply
• Excellent ESD survivability: 5kV HBM, 350V MM, 2kV CDM
Applications
• Industrial process control
•Energy measurement
• Multichannel data acquisition systems
• Pressure sensors
• Flow controllers
