Overview
The AD7477AWARMZ-RL is a high-performance, low-power analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This 10-bit successive-approximation ADC is designed to convert analog signals into digital signals at a throughput rate of up to 1 million samples per second (MSPS). The device operates from a single power supply ranging from 2.35 V to 5.25 V, making it versatile for various applications. It features a low noise, wide bandwidth track-and-hold amplifier and supports high-speed serial interfaces such as SPI, QSPI, MICROWIRE, and DSP-compatible interfaces.
