ADC driver for precision data-acquisition chains
The LTC6401IUD-20#PBF is an ADC driver from Linear Technology, purpose-built to condition analog signals before a data converter. Its Type is ADC Driver, meaning it is optimised for driving the switched-capacitor input of a high-speed ADC — not a general-purpose op-amp. The part targets Data Acquisition applications where signal integrity and settling time matter.
Package and footprint — 16-QFN with exposed pad
Housed in a 16-WFQFN Exposed Pad package (Supplier Device Package 16-QFN, 3x3 mm), this is a surface-mount device. The 16-pin QFN footprint is compact enough for dense mixed-signal boards but needs a decent copper pour underneath to pull heat out.
ROHS3 Compliant — no exemptions that complicate EU or California rework. For a storeroom keeper, this means you are not forced into a last-time-buy decision today; stock what you need and store the reels dry (MSL rating not in evidence, but QFN packages typically run MSL 1 or 3 — check the bag label).
