AD9643BCPZ-170

AD9643BCPZ-170 is a data acquisition type analog to digital converter. It is specifically designed to deliver 10-bit resolution at a fast sampling rate of 170MSPS. For applications where high integration and low power consumption are essential, this ADC provides superior performance. It is suitable for use in communication systems, medical imaging and test equipment, industrial automation, and automotive applications.

The AD9643BCPZ-170 is a single-channel monolithic ADC that features low distortion, low power, and a wide dynamic range. It operates from a 5V analog supply, a 3.3V digital supply, and an analog I/O voltage from 2.5V to 5V. It is powered by a low-power CMOS process and can achieve a 1.2V power consumption at 170MSPS. The ADC has a 10-bit data output, a dynamic range of 71.6 dB and a low distortion of 150 uVrms. The ADC is capable of sampling signals up to 170MHz, which makes it ideal for applications such as medical imaging and communications for high bandwidth digital data streams.

The AD9643BCPZ-170 is equipped with an on-chip digital filter, digital test logic, and a serial port output to enable wideband, low-power recording applications. The digital filter eliminates high-frequency noise and improves the signal-to-noise ratio. The digital logic test circuitry allows direct testing of the performance of the ADC. The serial port output provides parallel output data with a single clock, making it easier to transfer data out of the device and into other systems.

The ADC’s operating principle is based on a single-slope ADC with flash converter and two-stage sample and hold amplifier. In the first stage, the signal is held in a low-power track and hold and then stored in a charge-balanced capacitor array. The sample and hold amplifier is powered by a low-power CMOS process and is designed to accommodate large signal which ranges from 0V to 2.5V. The input signal is then clocked into the flash converter and is converted to 10-bits digital output. Any signals present in the time-frame of the hold stage are filtered and attenuated to improve the overall signal-to- noise ratio.

In addition to its fast performance and wide dynamic range, the AD9643BCPZ-170 is well suited for power sensitive applications due to its low power consumption. It features an automatic power down mode when not in use, saving the power supplies current levels. The ADC includes an on-chip reference current source and temperature sensor, both of which reduce power consumption. The temperature sensor can detect a signal’s temperature rise and shuts down the ADC when the signal is not needed.

In conclusion, the AD9643BCPZ-170 is a great example of an advanced analog to digital converter. It is versatile and easy to use, while providing high performance and low power consumption. It can be used with a variety of applications, including medical imaging, communications systems, test equipment, industrial automation, and automotive applications.
