ADC12J2700NKE Description

The ADC12J2700NKE from Texas Instruments is a high-performance 12-bit analog-to-digital converter (ADC) designed for ultra-high-speed signal acquisition. Operating at a staggering 2.7 GSPS (giga-samples per second), this ADC leverages a folding interpolating architecture to achieve exceptional dynamic performance while minimizing power consumption. It features a single-channel differential input with a 1:1 sample-and-hold (S/H) to ADC ratio, ensuring precise signal capture. The device supports a JESD204B serial interface, enabling seamless integration with high-speed digital systems. With dual-supply operation (1.14V–1.26V analog, 1.8V–2V digital), it balances power efficiency and signal integrity, making it ideal for demanding RF and mixed-signal applications. Packaged in a 68-VQFN tube, it is RoHS3 compliant and rated for MSL 3 (168 hours) moisture sensitivity.
