The 16-WFQFN exposed-pad package (3×3 mm, 0.5 mm pitch) keeps the signal path short — critical for preserving linearity at the frequencies where this driver operates. The LTC6401 family offers multiple fixed-gain versions. The -20 suffix indicates a specific gain setting; the LTC6401CUD-26#PBF is a sibling with a different gain value. Both share the same 16-QFN footprint and pinout, so swapping between them on the same PCB layout is straightforward — no board spin required. The I-grade variants (LTC6401IUD-26#PBF, LTC6401IUD-14#PBF) extend the temperature range. If your system already runs the commercial-temperature CUD-20, the pin-compatible IUD-26 or IUD-14 is a drop-in if the gain target shifts or the ambient envelope widens.","metaTitle":"LTC6401CUD-20#PBF ADC Driver, 16-QFN, Active","metaDescription":"Analog Devices LTC6401CUD-20#PBF ADC Driver in 16-WFQFN exposed pad.
