The device can be configured to have two differential inputs or four pseudo differential inputs. The on-chip channel sequencer allows several channels to be enabled, and the AD7192 sequentially converts on each enabled channel. This simplifies communication with the part. The on-chip 4.92 MHz clock can be used as the clock source to the ADC or, alternatively, an external clock or crystal can be used. The output data rate from the part can be varied from 4.7 Hz to 4.8 kHz.
The device has two digital filter options. The choice of filter affects the rms noise/noise-free resolution at the programmed output data rate, the settling time, and the 50 Hz/60 Hz rejection. For applications that require all conversions to be settled, the AD7192 includes a zero latency feature.
The part operates with a power supply from 3 V to 5.25 V. It consumes a current of 4.35 mA. It is housed in a 24-lead TSSOP package.

The EVAL-AD7192EBZ is a fully featured evaluation Board for the AD7192. The evaluation board can be operated in standalone mode ( either battery-powered or with external power supply) or connected to a PC via a standard USB interface. When operated with a PC, software is provided enabling the user to perform detailed analysis of the ADC's performance.
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.
