ISL26320, ISL26321, ISL26322, ISL26323, ISL26324, ISL26325, ISL26329
12-Bit, 250kSPS Low-Power ADCs with Single-Ended and Differential Inputs and Multiple Input
Channels
The ISL26320, ISL26321, ISL26322, ISL26323, ISL26324,
ISL26325 and ISL26329 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 The ISL26320, ISL26321, ISL26322,
ISL26323, ISL26324, ISL26325 and ISL26329 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 15mW at a sampling rate of
250kSPS, and an operating current of just 8ВµA typical
between conversions, when configured for Auto Power-down …
