Using the EVM Software

The crossover frequency for the 2-band DRC by default is 300Hz. This can be modified by entering a new

value in the property window.

The DRC rates for the softening filter, attack, and release can also be adjusted. To set these rates, first

click on the UPPERBAND or LOWERBAND block. Second, set the RateSliders property to On for that

block. Third, double-click on the block to bring up an advanced DRC options window, as shown in

Figure 15.

PBTL Mode: To run the device in PBTL Mode, the PBTL pin must be driven high. Then in the GUI, select

woofer instead of stereo (stereo is the default value). The source for PBTL is selected as (L+R)/2, but that

be changed by updating input mixer values.

3.6.1 MODULATION SCHEMES

Using The FAULT PIN As An Error Indicator:

The A_SEL_FAULTZ pin is the I

C device address select by default. To re-define this pin as an output,

write '1' to bit D1 of reg 0X05. Once re-programmed as output, this pin indicates a fault condition. Output

will go low for Overcurrent (OC) or undervoltage (UVP) error or overtemperature error (OTE) or

overvoltage error

Common Configurations:

1. 2 × BTL BD Mode

2. 2 × BTL AD Mode

Note:

AD: AD Modulation-Outputs are 180° out of phase

BD: BD Modulation

BTL: Bridge-Tied Load
