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, which provides design flexibility in a wide variety of applications. The ISL267452 also 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), making the ISL267452 an excellent solution for remote industrial sensors and battery-powered instruments.
The ISL267452 is available in an 8 LD SOT-23 package, and is specified for operation over the Industrial temperature range (-40°C to +85°C).
