The ISL267817IBZ-T is a 12-bit, 200kSPS sampling SAR ADC designed for applications requiring high accuracy and low power consumption. It features a fully-differential input that minimizes errors from leakage currents and maintains measurement accuracy with input signals up to the supply rails. The reference voltage range is flexible, accepting inputs from 0.1V to 2.5V, making it suitable for various applications. This ADC operates from a 5V supply with a power dissipation of 2.15mW at the maximum sampling rate, and it can reduce power consumption to just 25¬µW in Auto Power-Down mode, which is advantageous for battery-operated devices. The device is specified for an industrial temperature range of -40¬8C to +85¬8C and offers up to 8kV ESD protection. The serial digital interface is SPI compatible, facilitating easy integration with FPGAs and microcontrollers. The ISL267817IBZ-T is available in compact 8 Lead SOIC and MSOP packages, providing options for space-constrained designs.
The ISL267817 is a 12-bit, 200kSPS sampling SAR-type ADC which features excellent linearity over supply and temperature variations, and provides a drop-in compatible alternative to all ADS7817 performance grades. 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 between 0.1V to 2.5V, providing design flexibility in a wide variety of applications. The ISL267817 also features up to 8kV Human Body Model ESD survivability.
The serial digital interface is SPI compatible and is easily interfaced to popular FPGAs and microcontrollers. Operating from a 5V supply, power dissipation is 2.15mW at a sampling rate of 200kSPS, and just 25µW between conversions utilizing the Auto Power-Down mode, making the ISL267817 an excellent solution for remote industrial sensors and battery-powered instruments. It is available in the compact, industry-standard 8 Lead SOIC and MSOP packages and is specified for operation over the industrial temperature range (-40°C to +85°C).
