10-Bit and 12-Bit, 1MSPS SAR ADCs

ISL267440, ISL267450A

Features

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

• Drop-in Compatible with AD7440, AD7450A

• Differential Input

• Simple SPI-compatible Serial Digital Interface

• Guaranteed No Missing Codes

• 1MHz Sampling Rate

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.

• 3V or 5V Operation

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.

• Low Operating Current

- 1.25mA at 1MSPS with 3V Supplies

- 1.70mA at 1MSPS with 5V Supplies

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.

• Power-down Current between Conversions: 1µA

• Excellent Differential Non-Linearity

• Low THD: -83dB (typ)

• Pb-Free (RoHS Compliant)

• Available in MSOP Package

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).

Applications

• Remote Data Acquisition

• Battery Operated Systems

• Industrial Process Control

• Energy Measurement

• Data Acquisition Systems

• Pressure Sensors

• Flow Controllers
