Overview
The AD7859APZ-REEL, produced by Analog Devices Inc., is a high-speed, low-power, 8-channel, 12-bit analog-to-digital converter (ADC). This component is designed to operate from a single 3 V or 5 V power supply, making it versatile for various applications. The AD7859 is optimized for speed, offering a throughput rate of 200 kHz, while the AD7859L variant is optimized for low power consumption, with a throughput rate of 100 kHz. The ADC features self-calibration and system calibration options to ensure accurate operation over time and temperature. It also includes multiple power-down options to reduce power consumption in low-power applications.
