Frequently asked questions
What does the -40°C to 105°C rating mean for a closed-panel industrial application?
The -40°C to 105°C ambient rating applies at board level with the 48-LQFP thermal pad correctly soldered. In a sealed panel at 55°C ambient without forced airflow, the junction temperature on a still-air LQFP is a thermal-layout check against your specific board stackup and copper area — the 105°C rating is the limit, not a guarantee of margin at that ambient without thermal characterisation of the actual board.
Does the 6-channel 10-bit ADC map 1:1 to the existing terminal block wiring on a PLC sub-board?
The converter has 6 channels. Whether they land on the same terminal assignments as your current board depends on the original pinout — the 30 I/O in the 48-LQFP share the package pins with core functions (UART, SPI, PWM, QEI), so a 1:1 mapping to an existing wiring scheme requires a review of the board-level pin assignment against the LM3S818 datasheet before assuming drop-in compatibility on the I/O side.
