12-Bit Differential Input 200kSPS SAR ADC

ISL267817

Features

The ISL267817 is a 12-bit, 200kSPS sampling SAR-type ADC

which features excellent linearity over supply and temperature

variations, and provides a drop-in compatible alternative to all

ADS7817 performance grades. The robust, fully-differential

input offers high impedance to minimize errors due to leakage

currents, and the specified measurement accuracy is

• Drop-In Compatible with ADS7817 (All Performance Grades)

• Differential Input

• Simple SPI-compatible Serial Digital Interface

• Guaranteed No Missing Codes

• 200kHz Sampling Rate

maintained with input signals up to the supply rails.

• +4.75V to +5.25V Supply

The reference accepts inputs between 0.1V to 2.5V, providing

design flexibility in a wide variety of applications. The

ISL267817 also features up to 8kV Human Body Model ESD

survivability.

• Low 2.15mW Operating Power (200kSPS)

• Power-down Current between Conversions: 3µA

• Excellent Differential Non-Linearity (1.0LSB max)

• Low THD: -85dB (typ)

The serial digital interface is SPI compatible and is easily

interfaced to popular FPGAs and microcontrollers. Operating

from a 5V supply, power dissipation is 2.15mW at a sampling

rate of 200kSPS, and just 25µW between conversions utilizing

the Auto Power-Down mode, making the ISL267817 an

excellent solution for remote industrial sensors and

battery-powered instruments. It is available in the compact,

industry-standard 8 Lead SOIC and MSOP packages and is

specified for operation over the industrial temperature range

(-40°C to +85°C).

• Pb-Free (RoHS Compliant)

• Available in SOIC and MSOP Packages

Applications

• Remote Data Acquisition

• Battery Operated Systems

• Industrial Process Control

• Energy Measurement

• Data Acquisition Systems

• Pressure Sensors

• Flow Controllers
