12.5k SPS sampling rate — what it means for the design
At 12.5k samples per second, this ADC is sized for dc or slowly varying signals such as thermocouple outputs or battery voltage monitoring. The relaxed timing budget on the SPI bus reduces digital noise coupling into the analog section.
Lifecycle and sourcing
The LTC1286CN8#PBF is listed as Active in production status and is ROHS3 compliant. There is no last-time-buy or end-of-life notice, so the part can be specified into new designs without near-term obsolescence risk.
