The ADC34RF72 is a 16-bit, 1.5GSPS (non-interleaved), quad channel analog to digital converter (ADC). The device is designed for the highest signal-to-noise ratio (SNR) and delivers a noise spectral density of −163.7dBFS/Hz. Using internal averaging modes, the NSD can be improved to as low as -168.7dBFS/Hz. The buffered analog inputs support a programmable internal termination impedance of 50, 100, 200Ω with a full power input bandwidth of 1.8GHz (−3dB).

The device includes several digital processing features such as a 96-tap/ch programmable FIR filter for equalization, a 12-bit fractional delay filter as well as multiple digital down converters (DDCs). There are eight DDCs supporting decimation factors of /2, /3 and /5 up to /32768. The 48-bit NCOs support phase coherent frequency hopping.

The ADC34RF72 supports the JESD204B/C serial data interface with interface rates up to 24.75Gbps. The power efficient ADC architecture consumes 1.1W/ch at 1.5GSPS and provides power scaling with lower sampling rates.
