10-Bit and 12-Bit, 1MSPS SAR ADCs
ISL267440, ISL267450A
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 5W
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).
