12位10位和8位1msps SAR ADC,ISL26712, ISL26710, ISL26708

　　The ISL26712， ISL26710， ISL26708 are 12-bit， 10-bit and 8-bit， 1MSPS sampling SAR-type ADCs featuring excellent linearity over supply and temperature variations. 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， providing design flexibility in a wide variety of applications. The ISL26712/10/08 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. Power dissipation is 8.5mW at a sampling rate of 1MSPS， and just 5µW between conversions utilizing Auto Power-Down mode （with a 5V supply）， making the ISL26712/10/08 excellent solutions for remote industrial sensors and battery-powered instruments. The ISL26712/10/08 are available in an 8 Ld TDFN or an SOT-23 package， and are specified for operation over the Industrial temperature range （–40°C to +85°C）3.
