Other Parts Discussed in Thread: TEST
TAS2563 is applied in a stereo configuration per the reference design in Application Note slaa920. V-Sense data is placed on the shared TDM bus SDOUT1 with the following settings:
Left Register 0x0b = 0x40
Right Register 0x0b = 0x44
Other relevant information:
- SBCLK1 = SBCLK2 = 3.072 MHz
- FSYNC = 48 kHz
- There are 1 kΩ resistors in series with the VSNS_P and VSNS_N input pins.
The V-Sense data is present, however, its amplitude is very low. How can the amplitude be increased to avoid quantization noise?
EDIT: Attempted to change IVMON_LEN[1:0] from the default 16-bit configuration but longer/shorter bit configurations just appended 0's or truncated to MSB.
