What you are getting — 16 bits at 2.5 MSPS
The LTC2389CLX-16#PBF is a 16-bit SAR ADC sampling at 2.5 MSPS — fast enough for high-speed data acquisition, vibration analysis, or multi-channel multiplexed systems where one converter handles several inputs sequentially. It accepts both differential and pseudo-differential inputs, so you can wire it to a balanced sensor front-end or a single-ended signal chain without an extra driver stage. The data interface is SPI or parallel — pick SPI to save pins on a microcontroller or parallel for a tight-latency FPGA capture.
Package and board-fit — 48-LQFP, 7x7 mm
Supplied in a tray — no tape-and-reel, so if your pick-and-place line expects reeled parts, plan for a tray feeder or hand-place the first articles.
RoHS3 compliant — no exemptions for lead in solder, so it ships clean for EU and UKCA markets.
