The AD7861APZ is a 12-bit, successive approximation analog-to-digital converter (ADC) designed and manufactured by Analog Devices Inc. It offers high accuracy and performance with a variety of features that make it suitable for a wide range of applications.
One of the key features of the AD7861APZ is its 12-bit resolution, which allows it to convert analog signals into digital values with precision. This resolution is suitable for many applications that require accurate measurements, such as industrial control systems, data acquisition, and instrumentation.
The ADC operates with a single 5V power supply, making it compatible with a standard voltage source. This makes it easy to integrate into existing systems without requiring additional power supplies. Additionally, it offers a low power consumption of only 5mW, minimizing energy requirements for battery-powered applications.
The AD7861APZ supports a wide range of input analog voltage signals, spanning from ground potential to the positive supply voltage. It has an on-chip track-and-hold circuit, which samples and holds the input signal during the conversion process, ensuring accurate and stable conversions.
This ADC features both parallel and serial interface options, providing flexibility for different system requirements. The parallel interface can operate at high-speed rates, allowing for faster data transfer, while the serial interface uses a more efficient data transfer protocol.
To support accurate conversions across different conditions, the AD7861APZ incorporates an on-chip voltage reference and a precision internal clock
