ISL26712
ISL26712 is 1MSPS SAR ADC manufactured by Renesas.
ISL26712, ISL26710, ISL26708
12-Bit, 10-Bit and 8-Bit, 1MSPS SAR ADCs
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 8k V Human Body Model ESD survivability.
The serial digital interface is SPI patible and is easily interfaced to popular FPGAs and microcontrollers. Power dissipation is 8.5m W 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 SOT23 package, and are specified for operation over the Industrial temperature range (- 40°C to +85°C).
