Overview
The ADC12DL3200ACF is a high-performance, RF-sampling, giga-sample analog-to-digital converter (ADC) produced by Texas Instruments. This ADC is capable of directly sampling input frequencies from DC to above 10 GHz, making it highly versatile for various high-frequency applications. It operates in both single-channel and dual-channel modes, offering sampling rates of up to 6.4 GSPS in single-channel mode and up to 3.2 GSPS in dual-channel mode. The ADC12DL3200ACF features a low-latency, low-voltage differential signaling (LVDS) interface, which is particularly useful for latency-sensitive applications and simplifies synchronization across multiple devices.
