ISL267452 555kSPS SAR ADC

ISL267452 PIN NAME PIN NUMBER DESCRIPTION VDD 8 Supply voltage, +2.7V to 5.25V. SCLK 7 Serial clock input. Controls digital I/O timing and clocks the conversion. SDATA 6 Digital conversion output. CS 5 Chip select input. Controls the start of a conversion. GND 4 Ground VIN * 3 Ne.

ISL267452 12-Bit, 555kSPS SAR ADC The ISL267452 is a 12-bit, 555kSPS sampling SAR-type ADC featuring excellent linearity over supply and temperature variations, and is drop-in compatible with the AD7452. The robust, fully-differential input offers high impedance to minimize errors due to leakage currents, and the specified measurement accuracy is maintained with input signals up to the supply rails. The reference accepts inputs from 0.1V to 2.2V for 3V operation and 0.1V to 3.5V for 5V operation.

ISL267452 Features

* up to 8kV Human Body Model ESD survivability. The serial digital interface is SPI compatible and is easily interfaced to all popular FPGAs and microcontrollers. Power dissipation is 7mW at a sampling rate of 555kSPS, and just 5µW between conversions utilizing Auto Power-Down mode (with a 5V supply),
