ADS1205 - Two 1-Bit, 10MHz, 2nd-Order, Delta-Sigma Modulator ADC

Updated : 2020-01-09 14:28:32
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.
