lbuild module: modm:driver:ad7280a
The AD7280A is monitor for lithium ion battery packs with up to six cells. It contains six 12-ADCs with 1µs conversion per channel and a cell balancing interface. Up to 7 devices can be added through a Daisy-Chain interface (chain of 8 devices).
Recommended SPI Clk frequency is 1 MHz. With a 1 MHz Clk, it takes approximately 1.54 ms to read back the voltage conversions on 48 channels.
When addressing devices in the chain directly the frequency needs to be lower than 1 MHz because delays introduced in each stage of the chain.
