Overview
The AD7490WBCPZ-REEL7, produced by Analog Devices Inc., is a 12-bit, high-speed, low-power analog-to-digital converter (ADC) designed for a wide range of applications. This ADC features a successive approximation register (SAR) architecture and supports up to 1 million samples per second (MSPS). It operates from a single power supply ranging from 2.7V to 5.25V, making it versatile for various system designs. The device includes 16 single-ended analog inputs with a built-in channel sequencer, allowing for preprogrammed selection and sequential conversion of channels. This ADC is particularly noted for its low power consumption and high throughput rates, making it an efficient choice for applications requiring high-speed data acquisition.
