概述

Description

The AD7868BRZ is a high-performance, low-power, 8-channel, 12-bit analog-to-digital converter (ADC) designed by Analog Devices. It features a successive approximation architecture, allowing it to convert analog signals to digital form with high accuracy. The device operates with a single supply voltage ranging from 2.7V to 5.25V and supports an internal reference voltage.
Key features include a sampling rate of up to 100 kSPS and a parallel interface for fast data transfer, making it suitable for various applications, including industrial process control, medical instrumentation, and data acquisition systems. The AD7868BRZ also includes features like internal track-and-hold circuitry, low power consumption (typical operating current of around 500 µA), and a built-in power-down mode.
Overall, the AD7868BRZ is ideal for applications requiring precise and efficient analog signal conversion in compact, battery-operated devices.
