The ADS1209 is a two-channel, high-performance, delta-sigma () modulator with an 86dB dynamic range, operating from a single +5V supply. The differential inputs are ideal for direct connection to signal sources 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 accuracy of 14 bits can be obtained with a digital filter bandwidth of 20kHz at a modulator rate of 10MHz. The ADS1209 is designed for use in high-resolution measurement applications including current measurements, industrial process control, and resolvers. It is available in a TSSOP-24 package and is specified for operation over the ambient temperature range of –40°C to +105°C.
