Overview
The ADS54J60IRMPT is a dual-channel, 16-bit, 1.0-GSPS (gigasamples per second) analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for high-performance applications requiring low power consumption and high signal-to-noise ratio (SNR). It features a wide bandwidth and excellent spectral performance, making it suitable for various high-speed data acquisition systems.
The ADC supports the JESD204B serial interface with data rates up to 10 Gbps, allowing for high system integration density. It also includes a buffered analog input to provide uniform input impedance across a wide frequency range and minimize sample-and-hold glitch energy. Each ADC channel can optionally be connected to a wideband digital down-converter (DDC) block, enhancing its versatility in different applications.
