The AD7478AARM is a precision, low-power, 12-bit analog-to-digital converter (ADC) integrated circuit (IC) component from Analog Devices Inc. It is designed for various applications such as industrial automation, medical instruments, and sensor interfaces. This IC offers high performance, low power consumption, and a small footprint, making it suitable for space-constrained applications.
One of the key features of the AD7478AARM is its 12-bit resolution, allowing it to convert analog signals into digital data with high accuracy. It employs a successive approximation architecture, which enables fast conversion times of up to 1.7 MS/s (Mega-samples per second). This high-speed conversion capability is helpful in applications that require real-time data processing.
The AD7478AARM operates from a single power supply ranging from 2.7V to 5.25V, making it compatible with a wide range of power sources. Additionally, it offers a low power consumption of 0.65 mW at a conversion rate of 100 kSPS (kilo-samples per second), making it suitable for battery-powered devices or any application where power efficiency is crucial.
To further enhance its precision, the AD7478AARM includes an onboard 2.5V reference voltage source. This eliminates the need for an external reference, reducing the overall component count and simplifying the design process
