The broad application field of AD9266BCPZ-20 has provided the support to high performance in many fields.

Working principle

AD9266BCPZ-20 is an 8/10/12 bit ADC with 20MSPS, making it capable of achieving high resolution and high sampling rate.

AD9266BCPZ-20 features an integrated low noise input buffer, so it can directly input from different differential analog signals or single-end analog signals. It also features an internal voltage reference with a wide range option.

AD9266BCPZ-20 uses a highly accurate SAR (successive approximation register) architecture, which integrates several successive approximations with a single-slice comparison. During the conversion process of SAR, the number of least significant bits (LSB) of the digital output is compared with the analog input voltage to determine the value of the next bit.

The high speed and the low power consumption of AD9266BCPZ-20 are the result of its thin on-chip reconstruction filter and its active settling mode control. This thin on-chip reconstruction filter reduces the number of external components significantly, while the active settling mode control only requires 500nA of current. This makes AD9266BCPZ-20 suitable for a variety of complex application scenarios.

Conclusion

AD9266BCPZ-20 is an 8/10/12 bit ADC with 20MSPS that is particularly suitable for low power, small size and high sampling rate application scenarios. There are a significance number of application fields combining medical devices, commercial instrumentation, automotive products, communications, video, imaging and etc. The working principle of AD9266BCPZ-20 is based on the SAR (successive approximation register) architecture, and its thin on-chip reconstruction filter and active settling mode control achieved high speed and low power consumption.
