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 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).
