DATASHEET
ISL267440, ISL267450A
10-Bit and 12-Bit, 1MSPS SAR ADCs
The ISL267440 and ISL267450A are 10-bit and 12-bit, 1MSPS
sampling SAR-type ADCs featuring excellent linearity over
supply and temperature variations. These devices are drop-in
compatible with the AD7440 and AD7450A. 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. This provides
design flexibility in a wide variety of applications. The
ISL267440, ISL267450A also feature 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). The ISL267440, ISL267450A are excellent
solutions for remote industrial sensors and battery-powered
instruments.
The ISL267440, ISL267450A are available in an 8 lead MSOP
package, and are specified for operation over the Industrial
temperature range (–40°C to +85°C).
