12-Bit, 10-Bit and 8-Bit, 1MSPS SAR ADCs
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 5W
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).
