BelaSigna 200
9.2 External Analog Interfaces
9.2.1. Low-Speed A/D Converters (LSAD)
Six LSAD inputs are available on BelaSigna 200. Combined with two internal LSAD inputs (supply and ground) this gives a total of eight
multiplexed inputs to the LSAD converter. The multiplexed inputs are sampled sequentially at 1.6kHz per channel. The native data
format for the LSAD is 10-bit two's complement. However, a total of eight operation modes are provided that allow a configurable input
dynamic range in cases where certain minimum and maximum values for the converted inputs are desired; such as in the case of a
volume control where only input values up to a certain magnitude are allowed.
