TCD6000 – Rev. 1.0/09.04

When the GNn control bits are cleared to ‘0’, the TCD6000 operates in low post-gain mode. In this mode,

the noise floor is lowered but the system may not be able to obtain the maximum power output from the

power stage. When the GNn control bits are set to ‘1’, the TCD6000 operates in high post-gain mode. In this

mode, gain is increased by 25%. The system will now be able to obtain the maximum power output from the

power stage but the noise floor will have increased accordingly.

The BCn control bits control the method of automatic DC calibration that will be used. The BCn bits should

be set to ‘1’ if a bridged output stage is being used. The BCn bits should be cleared to ‘0’ if a single ended

output stage is being used. The BCn bits work in conjunction with the DCB bit. When DCB is set to '1', the

BCn bits should be set to '1'. When DCB is cleared to '0', the BCn bits should be cleared to '0'.
