NXP's ADC1415Sxxx is a single-channel 14-bit ADC that supports up to 125 MSPS sampling rates and features excellent dynamic performance, along with a low-power BiCMOS input buffer for use in high-IF applications.
The ADC1415Sxxx is a high‑performance, single‑channel 14‑bit analog‑to‑digital converter designed for high‑IF and broadband applications. It features a low‑power BiCMOS input buffer, selectable sample rates (65‑125 MSPS), and a SPI interface for easy configuration.
Typical applications include wireless and wireline broadband communications, spectral analysis, industrial imaging, ultrasound equipment, and portable high‑speed instrumentation. The device is supplied in an HVOFN4O package and operates from a single 3‑V supply, with the input buffer powered from 5 V.
