The AD7193 is an low power, flexible, high performance, ultra-low noise, 24 bit, Sigma Delta ADC suitable for converting low input bandwidth analog signals with a fully flexible ODR (output data rate) between 4.7SPS to 4.8kSPS
There is an on-chip low noise gain stage which allows signals of small amplitude to interface directly to the ADC.
The AD7193 combines 4 differential or 8 pseudo differential input channels with low power figures.
With an ODR of 4.7sps and a gain of 128 the AD7193 can boast RMS noise of 11nV.
The AD7193 is user friendly, with full part configuration available over a 3 wire serial interface.
The AD7193 comes in a 28 lead TSSOP package and a 32 lead LFCSP package.
- Mains power supply interference Simultaneous 50Hz and 60Hz rejection at 50SPS ODR

Virtual Eval - BETA
Virtual Eval is a web application to assist designers in product evaluation of ADCs and DACs. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, frequency response plots, and more.
