The EVAL-AD7280AEDZ has cell balance turned on even with register 0x14 set to 0x00 and all the CB registers set to 0. This is on a test bench with resistors simulating a 12 cell battery that start with a very uniform voltage drop across each resistor. the EVAL drives more than a 0.5 volt from the slave to the master AD7280 so the voltage drop across the slave resistors is 0.5V less than the master resistors. I have tried writing all of the registers and still cannot turn this off. I cannot connect this EVAL to an actual set of battery cells without being able to control the cell balance.
