SBAS958A December 2019 – June 2020 ADC3421-Q1
PRODUCTION DATA.
The ADC3421-Q1 analog signal inputs are designed to be driven differentially. Each input pin (INP, INM) must swing symmetrically between (VCM + 0.5 V) and (VCM – 0.5 V), resulting in a 2-VPP (default) differential input swing. The input sampling circuit has a 3-dB bandwidth that extends up to 540 MHz (50-Ω source driving 50-Ω termination between INP and INM).
