(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.




Description

The ADS1205 is a two-channel, high-performance, delta-sigma () modulator with more than 98dB dynamic range, operating from a single +5V supply. The differential inputs are ideal for direct connection to transducers in an industrial environment. With the appropriate digital filter and modulator rate, the device can be used to achieve 16-bit analog-to-digital (A/D) conversion with no missing codes. Effective resolution of 14 bits can be obtained with a digital filter bandwidth of 40kHz at a modulator rate of 10MHz. The ADS1205 is designed for use in high-resolution measurement applications including current measurements, smart transmitters, industrial process control, and resolvers. It is available in a QFN-24 (4x4) package.
