Description

The ADS1210 and ADS1211UG4 are precision, wide dynamic range, delta-sigma analog-to-digital converters with 24-bit resolution operating from a single +5V supply. The differential inputs are ideal for direct connection to transducers or low level voltage signals.The delta-sigma architecture is used for wide dynamic range and to guarantee 22 bits of no missing code performance. An effective resolution of 23 bits is achieved through the use of a very low-noise input amplifier at conversion rates up to 10Hz. Effective resolutions of 20 bits can be maintained up to a sample rate of 1kHz through the use of the unique Turbo modulator mode of operation. The dynamic range of the converters is further increased by providing a low-noise programmable gain amplifier with a gain range of 1 to 16 in binary steps. ADS1211UG4 Features • Delta-sigma a/d converter• 23 bits effective resolution at 10hz and 20 bits at 1000hz• Differential inputs• Programmable gain amplifier• Flexible spi compatible ssi interface with 2-wire mode• Programmable cut-off frequency up to 15.6khz• Internal/external reference• On chip self-calibration• Ads1211 includes 4 channel mux ADS1211UG4 Applications • Industrial process control• Instrumentation• Blood analysis• Amart transmitters• Portable instruments• Weigh scales• Pressure transducers
