Overview
The ADC32RF80IRMPR, part of the ADC32RF8x family, is a 14-bit, dual-channel, 3-GSPS telecom receiver and feedback device produced by Texas Instruments. This device is designed for high signal-to-noise ratio (SNR) and supports RF sampling with input frequencies up to 4 GHz. It features a noise spectral density of –155 dBFS/Hz and high dynamic range, making it suitable for various telecommunications applications. The ADC32RF80IRMPR includes on-chip digital down-converters, input clamps for overvoltage protection, and programmable power detectors with alarm pins for automatic gain control (AGC) support. The device is available in a 72-pin VQFN package and supports the industrial temperature range (–40°C to +85°C).
