Overview
The AD7880BR-REEL is a high-resolution, low-power analog-to-digital converter (ADC) produced by Analog Devices Inc. This 12-bit ADC is designed for high-speed data acquisition applications and features a successive approximation register (SAR) architecture. It operates with two parallel channels and supports single-ended inputs. The device is known for its fast conversion rate, low noise performance, and the ability to operate over a wide temperature range of -40°C to 85°C. Although the AD7880BR-REEL has been discontinued and is no longer recommended for new designs, it remains a significant component in existing systems due to its performance and reliability.
