1821TH Datasheet (Inphi) - 18-GHz Bandwidth 2-GS/s THA

1821TH, 18-GHz Bandwidth 2-GS/s THA

The 1821TH track-and-hold amplifier is designed for high-precision sampling of wideband signals with multi-GHz frequency content.

The masterslave architecture integrates two track-and-hold circuits, a 50-ohm differential output buffer, and clock mode selection logic.

Sample rates up to 2 GS/s are su
