Overview
The ADS54J69IRMPT is a low-power, wide-bandwidth, 16-bit, 500-MSPS (Mega Samples Per Second), dual-channel analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed to deliver high signal-to-noise ratio (SNR) and excellent spurious-free dynamic range (SFDR) over a large input frequency range. It features a noise floor of –159 dBFS/Hz, making it suitable for applications requiring the highest dynamic range over a wide instantaneous bandwidth.
