PRODUCTION DATA
For systems that do not require the advanced flexibility of the I2C registers control or does not have an available I2C host controller, the TAS5830 can be used in Hardware Control Mode. Then the device operates in Hardware mode default configurations and any change is accomplished via the Hardware control pins. The audio performance between Hardware and Software Control modes with the same configuration is identical, however, more features are accessible under Software Control Mode through registers.
Several I/O's on the TAS5830 needs to be taken into consideration during schematic design for desired start up settings. The method for going into Hardware Control Mode is to pull high HW_MODE pin 8 to DVDD.
The TAS5830 default Hardware configuration is BTL mode, 768kHz switching frequency, 1SPW mode, 175kHz Class D amplifier loop bandwidth, 29.5Vp/FS analog gain, CBC threshold with 80% of OCP threshold. It requires the HW_SEL0 pin 16 and HW_SEL1 pin 15 directly tied to GND.
