Panel Setup Timing Configuration Register (0x05)
Note: These settings apply to measurement commands, combined commands, and autonomous conversion mode measurements
and provide time for the panel to settle prior to beginning measurements. During these periods, the panel is set up, but the ADC
remains powered down. Users with low-impedance/fast settling panels should use setting 0000 (skip mode) if their panel can be set-
tled during the required 10μs minimum delayed conversion time (see the Delayed Conversion Configuration Register (0x06) section).
Delayed Conversion Configuration Register (0x06)
Note: These settings apply to measurement commands, combined commands, and autonomous conversion mode measurements
and provide time for the panel and ADC to settle prior to beginning measurements. During these periods, the panel is set up and the
ADC is powered up. In general, users with long panel settling requirements should minimize time in this mode, using increased
panel setup times instead to save ADC power.
