Overview
The ADS5562IRGZT is a high-performance 16-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS556x family, which includes the ADS5560 and ADS5562 models, offering sampling rates of up to 80 MSPS. The ADS5562IRGZT is designed to provide very high signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR) for input frequencies in the first Nyquist zone. It features a compact 48-pin VQFN package, making it suitable for applications where space and power efficiency are critical.
