ISL26712, ISL26710, ISL26708

12-Bit, 10-Bit and 8-Bit, 1MSPS SAR ADCs

FN7999

Rev 3.00

September 5, 2012

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,

Features

• Differential Input

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.

• 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, providing design

flexibility in a wide variety of applications. The

ISL26712/10/08 also features 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

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), making the ISL26712/10/08 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 TDFN Package (3x3mm)

• Available in SOT-23 Package

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).

Applications

• Remote Data Acquisition

• Battery Operated Systems

• Industrial Process Control

• Energy Measurement

• Data Acquisition Systems

• Pressure Sensors

• Flow Controllers
