DATASHEET  
ISL267440, ISL267450A  
10-Bit and 12-Bit, 1MSPS SAR ADCs  
FN7708  
Rev.2.00  
June 28, 2012  
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.  
Features  
• Drop-in Compatible with AD7440, AD7450A  
• Differential Input  
• Simple SPI-compatible Serial Digital Interface  
• Guaranteed No Missing Codes  
• 1MHz Sampling Rate  
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.  
• 3V or 5V Operation  
• Low Operating Current  
- 1.25mA at 1MSPS with 3V Supplies  
- 1.70mA at 1MSPS with 5V Supplies  
• Power-down Current between Conversions: 1µA  
• Excellent Differential Non-Linearity  
• Low THD: -83dB (typ)  
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.  
• Pb-Free (RoHS Compliant)  
• Available in MSOP Package  
Applications  
• Remote Data Acquisition  
• Battery Operated Systems  
• Industrial Process Control  
• Energy Measurement  
• Data Acquisition Systems  
• Pressure Sensors  
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).
