SLAAEM6 October 2025 TAS2120
A reference shared boost system was configured for an analog gain of 18dBV on both TAS2120 and TAS2320. The schematic and PCB design information for this hardware implementation is available in Reference Shared Boost System.
Figure 3-1 shows the distortion and output power performance obtained using this setup. This shows that when only one of the amplifiers is driving the speaker, the undistorted output is higher, whereas driving both speakers equally at the same time can split the total power for each channel.
