The AD5821ABCBZ-REEL is an integrated circuit (IC) component developed by Analog Devices. It is a high-performance, 16-channel, digitally controlled potentiometer (DCP) designed for various applications. The IC operates with a supply voltage ranging from 2.7V to 5.5V, making it suitable for portable devices and industrial systems.
One of the key features of the AD5821ABCBZ-REEL is its precise resistor array, which provides accurate resistance values for each channel. It offers a resistance range of 5 kilohms to 100 kilohms, enabling a wide range of applications. The IC is capable of achieving an excellent linearity performance of ±1 %, ensuring high precision in resistance control.
Another notable feature of the AD5821ABCBZ-REEL is its digital interface, which allows for easy control and programming. It utilizes a serial peripheral interface (SPI) for communication, providing a straightforward protocol for users to access and configure the potentiometer's settings. This digital control simplifies the integration process and enables precise adjustments.
Flexibility is a key advantage of this IC, as it allows users to easily select the desired channels to adjust. The AD5821ABCBZ-REEL provides an input control register that enables independent selection of each channel for resistance changes. This flexibility is beneficial in applications where multiple potentiometers need to be controlled individually
