So what is the big deal about the AD4170 and why is it important? Well to put is mildly, this is a leap forward in performance and integration. We took the best learning from the AD7124 (already a huge leap forward in Integration and performance for Sigma-Delta ADC) and focused on optimizing the noise and input bandwidth whilst adding additional smarts for ease of customer use. The integrated PGA is extremely low noise, to enable much better signal capture, the 50KHz input BW enables the measurement of AC signals for Structural Health or Condition Monitoring and the integrated, user programmable FIR filter allows the customers to remove extraneous information in the ADC, without having to load the system uC or transmit superfluous data. The AD4170 is the next generation of Intelligent Edge Converters from Analog Devices and augments our Precision Sigma-Delta product portfolio.
ADI announces the release of our new ground-breaking AD4170-4 Analog to Digital Converter (ADC), delivering unprecedented levels of Signal-chain integration and Bandwidth support. The AD4170 is a precision 24-bit ultra-low noise, 4-Channel (4 Diff/8 SE), DC to 50kHz Input BW Sigma-Delta ADC, with integrated PGA, Voltage Reference, Smart Sequencer, extensive Diagnostic functionality, flexible Filter options that also includes a user Programmable FIR Filter, and an integrated DAC for flexible sensor excitation. This product sets new standards for AC and DC performance for Instrumentation & Industrial Measurement applications: • Noise Density 5.5nV/√Hz, • Gains of 0.5 - 128 • ODR 7.6 SPS to 500 kSPS • THD –120 dB. The AD4170-4 allows for a system design platform for sensor clusters, resolving multiple diverse sensor inputs to a common platform, with exceptional precision.

4moDoes it support Group conversions ...? Several group of channels simultaneously getting converted and the result we get after different cycle times based on requirements...can it be integrated with DMA transfers with end of conversion interrupts ?
