Overview
The ADS54J69IRMP is a low-power, wide-bandwidth, 16-bit, 500-MSPS, dual-channel analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for high signal-to-noise ratio (SNR) and delivers a noise floor of –159 dBFS/Hz, making it suitable for applications requiring the highest dynamic range over a wide instantaneous bandwidth. The ADS54J69IRMP supports the JESD204B serial interface with data rates up to 10.0 Gbps and features integrated decimate-by-2 filters and on-chip dither. The buffered analog input provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy. Each ADC channel is directly connected to a wideband digital down-converter (DDC) block, ensuring excellent spurious-free dynamic range (SFDR) with very low power consumption.
