It is suitable for use in a variety of high-performance data acquisition applications such as telecommunications, industrial process control, medical imaging, test and measurement applications. It is also suitable for image sensing and image post-processing in industrial, medical and scientific applications.

The underlying working principle of the AD9680BCPZ-1250 is based on the conversion of an analog signal into a digital form. The analog signal is first fed into an input circuit, which contains an operational amplifier and an analog switch, and is then amplified and buffered. This is followed by a sigma-delta modulator circuit, which is the core of the ADC and performs the actual conversion from analog to digital. The sigma-delta modulator operates on the principle of delta-sigma (ΔΣ) modulation and converts the analog signal, with high resolution and dynamic range, into a pulse-coded digital signal. This pulse-coded digital signal is then further converted into a two’s complement data format which is the commonly used digital representation   of the analog signal.

The AD9680BCPZ-1250 is a high-performance, power-efficient, single-channel ADC with excellent dynamic and low-noise performance. It is suitable for a variety of data acquisition applications and its embedded PGA and on-chip noise filtering features make it well suited for use in high-resolution imaging and post-processing applications. With its single-ended or differential analog inputs, dual 12-bit output and low operating voltage, the AD9680BCPZ-1250 ADC is the ideal choice for a variety of applications.
