SBAS809A – FEBRUARY 2017 – REVISED MARCH 2017 ADC32RF44 Dual-Channel, 14-Bit, 2.6-GSPS, Analog-to-Digital Converter
1 Features 3 Description The ADC32RF44 device is a 14-bit, 2.6-GSPS, dualchannel, analog-to-digital converter (ADC) that
supports RF sampling with input frequencies up to
4 GHz and beyond. Designed for high signal-to-noise
ratio (SNR), the ADC32RF44 delivers a noise
spectral density of –154.2 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. 14-Bit, Dual-Channel, 2.6-GSPS ADC
Noise Floor: –154.2 dBFS/Hz
RF Input Supports Up to 4.0 GHz
Aperture Jitter: 90 fS
Channel Isolation: 95 dB at fIN = 1.8 GHz
Spectral Performance (fIN = 900 MHz, –2 dBFS):
– SNR: 61.2 dBFS …
