ISL26320FBZ集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

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 singleended 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 8µA typical between

conversions, when configured for Auto Power-down mode.

The ISL26320, ISL26321, ISL26322, ISL26323, ISL26324,

ISL26325 and ISL26329 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).
