Product Description

AD7893BR-10 Analog-to-Digital Converter (ADC)

The AD7893BR-10 is a high-performance, low-power 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) developed by Analog Devices. Designed for precision signal conversion in industrial, instrumentation, and embedded systems, it offers an optimal balance of accuracy, speed, and energy efficiency. The "BR-10" suffix indicates a 10 µs maximum conversion time and wide operating temperature range, making it ideal for dynamic and harsh-environment applications.
