The AD7846APZ is an integrated circuit (IC) component developed by Analog Devices. It is a complete, dual-channel, serial input for analog-to-digital (ADC) conversion with an on-chip reference and sequencer. The AD7846APZ offers high performance and flexibility, making it ideal for a wide range of industrial, medical, and automotive applications.
One of the key features of the AD7846APZ is its dual-channel capability, allowing simultaneous conversion of two analog input channels. This feature enables faster and more efficient data acquisition in multi-channel systems. The chip also offers a wide analog input voltage range of +/- 10V, making it suitable for a variety of sensor interfaces.
The AD7846APZ utilizes a 14-bit resolution ADC, providing accurate and precise conversion of analog signals into digital data. The on-chip sequencer allows programmable channel sequencing, enabling sequential ADC conversions and simplifying the system control. This sequencing feature is highly beneficial for applications requiring sequential measurements from multiple sensors, where a single ADC can be shared between different channels.
To ensure accuracy and linearity in the conversion process, the chip incorporates a voltage reference. This helps compensate for any variations and fluctuations in the input voltage, ultimately improving the overall precision of the ADC. Furthermore, the AD7846APZ offers a flexible serial interface, supporting both serial peripheral interface (SPI) and microwire protocols
