The AD7840JPZ is an integrated circuit (IC) component manufactured by Analog Devices. It is a complete signal conditioning subsystem designed for interfacing different types of sensors with microcontrollers or digital systems. The IC is known for its versatility and reliable performance in various applications. Here is an overview of the AD7840JPZ along with its key features:
1. Conversion Capability: The AD7840JPZ offers 14-bit resolution successive approximation analog-to-digital conversion. It performs accurate and precise conversions of analog signals into digital data.
2. Input Channels: It features eight differential input channels, which allows it to connect with multiple sensors or analog sources simultaneously. The differential inputs enable the measurement of both voltage and current signals.
3. Programmable Gain Amplifier (PGA): The IC includes a programmable gain amplifier that offers four selectable gain settings of 1, 2, 4, and 8. The PGA provides flexibility in amplifying weak signals for better signal conditioning.
4. Sample and Hold: The AD7840JPZ incorporates a sample-and-hold circuitry that captures and holds the analog input voltage during the conversion process. This eliminates the need for external sample-and-hold circuitry, simplifying the overall design.
5. Serial Interface: It communicates with external devices using a serial interface based on a high-speed, 4-wire, SPI-compatible protocol. This allows seamless integration with microcontrollers or digital systems
