-1

LSB

Note: This is

 4 LSBs for the 14-bit A-to-D conversion. This results in absolute accuracy to 12-bits on the A-to-D result. Non-linearity is

typically better at temperatures less than 125°C.

* No verification in mass production; parameter is guaranteed by design and/or quality observation.
