Texas Instruments ADC32RF80
The ADC32RF8x (ADC32RF80 and ADC32RF83) is a 14-bit, 3-GSPS, dual-channel telecom receiver and feedback device family that supports RF sampling with input frequencies up to 4 GHz and beyond. Designed for high signal-to-noise ratio (SNR), the ADC32RF8x family delivers a noise spectral density of –155 dBFS/Hz as well as dynamic range and channel isolation over a large input frequency range. The buffered analog input with on-chip termination provides uniform input impedance across a wide frequency range and minimizes sample-and-hold glitch energy.FEATURES
