AD7176-2BRUZ 24-bit, 250 KSPS Sigma-Δ ADC with 20μS settling time
The AD7176-2 is a fast-settling, high-accuracy, high-resolution, multiplexed, 24-bit Sigma-Δ ADC with a low-bandwidth input signal with a fully flexible ODR (output data rate) between 5SPS and 250kSPS.
The AD7176-2 combines 2 differential or 4 single-ended analog input channels via an integrated crosspoint multiplexer with industrial beat power graph.
For 50 Hz and 60 Hz environments, the AD7176-2 specific filters minimize settling time or provide the strongest line frequency rejection. These enhanced filters feature simultaneous 50Hz and 60Hz rejection with an output data rate of 27SPS.
The AD7176-2 has an ODR of 250ksps and a noise of 9.7uV at RMS when running on the default Sinc5+Sinc1 filter.
The AD7176-2 is configured via SPI in a small 24-pin TSSOP package that reduces board size.
The integrated precision 2.5V (2 ppm/°C) reference and integrated oscillator increase functionality and reduce the number of external components.
