AD7927 is a 12 bit, high-speed, low-power, 8-channel, successive approximation ADC that uses a single power supply ranging from 2.7 V to 5.25 V, with a maximum throughput of 200 kSPS. This device is equipped with a low noise, wide bandwidth sampling and holding amplifier, which can handle input frequencies above 8 MHz The conversion and data acquisition processes are controlled through CS and serial clock signals, creating conditions for easy interface between devices and microprocessors or DSPs. The input signal is sampled at the falling edge of CS, and the conversion is initiated at this point. This device has no pipeline delay AD7927 adopts advanced design techniques to achieve extremely low power consumption at the highest throughput. At the highest throughput, when using a 3V power supply, the maximum power consumption of AD7927 is 1.2 mA; When using a 5 V power supply, the maximum power consumption is 1.5 mA
