AD9608BCPZ-105 is an Analog to Digital Converter (ADC) in the data acquisition field. It is a high-performance, precision, low noise and cost-effective ADC, allowing design engineers to gain greater precision and performance at a lower cost. The AD9608BCPZ-105 is capable of digitizing signals with 0.5 LSB noise, 8-bit resolution and a dynamic range of 105dB.

Application Field

The AD9608BCPZ-105 is designed for a wide variety of data acquisition applications including ultrasound, radar, ultrasound imaging, medical imaging, motion control and image sensors. It is particularly suitable for wide dynamic range requirements of data acquisition system, on the other hand, its low cost makes it attractive for consumer applications too. Examples of such applications include medical imaging, voice recognition, 3D scanners, surveillance cameras, robotics and automotive sensors. The AD9608BCPZ-105 can be used in any application requiring high precision with an AD conversion speed of up to 42MSPS.

Design Specifications

AD9608BCPZ-105 features an input sampling rate of up to 42MSPS, an 8-bit resolution, a dynamic range of up to 105dB and 0.5 LSB noise. The AD C noise level is at least 2 dB better than conventional ADCs. With its integrated self-calibration block and integrated loop filter, the device can accurately sample input signals over the entire 128-bit field for both single and multiplexed data flows. Additionally, it is designed to allow operation at very low power levels across a wide range of input frequencies. The AD9608BCPZ-105 also features a paralleling capability that allows for higher-resolution conversions without adding more external components. All these characteristics make it an ideal choice for a wide range of applications.

Working Principle

The working principle of the AD9608BCPZ-105 is based on the successive approximation principle. During operation, the ADC samples the incoming signal with an input delay of 256 bits. The first step of the conversion is to measure the amplitude of the incoming signal and compare it with the reference voltage. Then, using the successive approximation algorithm, the ADC calculates the voltage mapping from input sample to 5-bit digital output. After that, the ADC works the same way for the remaining 7 bits, outputting a sequence of 7-bit codes to the digital output bus. Finally, the ADC calibrates each conversion according to the programmed reference voltage and internal timing signals for accuracy.

Conclusion

In summary, the AD9608BCPZ-105 is an ideal analog-to-digital converter for high-performance, precision, low noise and cost-effective applications. It features an input sampling rate of up to 42MSPS, an 8-bit resolution, a dynamic range of up to 105dB and 0.5 LSB noise. Signals with a wide dynamic range can be accurately digitised with very low power consumption. Thanks to its integrated self-calibration block and integrated loop filter, the device can accurately sample input signals over the entire 128-bit field for both single and multiplexed data flows.
