Data acquisition is the process of converting analog signals into digital information. To perform this, various types of analog-to-digital converters (ADCs) are used to convert analog signals into digital signals for the purpose of processing, storage and transmission. The AD7264BCPZ-5 is a high-performance and cost-effective CMOS analog-to-digital converter, providing excellent performance in terms of acquisition speed, conversion accuracy, power dissipation and immunity to RF interference.

The AD7264BCPZ-5 is an 8-channel monolithic ADC, with a power supply voltage of 3.3V. It is an 8-bit Get‑A‑Bit (GAB) type SAR ADC, providing a sampling rate of up to 1Msps. It has a 14-bit accuracy and a dynamic range exceeding 140dB. The AD7264BCPZ-5 utilizes a folded-van-integrated circuit topology, providing a high-speed conversion time and low power consumption, while still achieving exceptional performance in terms of power dissipation and SNR.

The AD7264BCPZ-5 is a low-noise ADC suitable for use in all types of embedded applications, including medical, industrial, automotive, aerospace and consumer applications. It can also be used for high-precision test and measurement, soil monitoring, and wearables. The ADC operates over an extended temperature range, from -40°C to +125°C.

The AD7264BCPZ-5 is fast, low-power, low-noise and efficiently scalable for multi-channel systems. It has an integrated sample-and-hold circuit, multiplexer and voltage reference. The on-chip reference has a range of 25mV to 3.00V, making it suitable for a wide variety of input signal levels. The multiplexer allows the user to select any of the 8 channels by setting the MUX register, while limiting the signal bandwidth to 500kHz.

The AD7264BCPZ-5 is a pin-compatible upgrade of the popular AD7248BCPZ-5 model, offering improved performance and a simpler interface. It uses a patented Parallax Error Cancellation (PEC) technique to reduce system errors due to parasitic capacitance in the analog signals and allow for higher speed conversions with improved accuracy. The PEC technique allows the ADC to operate in two modes: low-noise or fast mode. In low-noise mode, the ADC can achieve a maximum input frequency of 500kHz; whereas in fast mode, the maximum input frequency is doubled to 1MHz.

The AD7264BCPZ-5 is a versatile, high-performance, cost-effective ADC suitable for use in a wide variety of applications. Its advanced features and low power consumption make it a good choice for any embedded system where speed and accuracy are required.
