Table 1. Key Parameters
Key Parameters
Power Supply Voltage 8 V to 26 V
Number of Channels Two Bridge-Tied Load (BTL) Stereo or One Parallel BTL (PBTL) Mono
Load Impedance Stereo BTL 4 Ω to 8 Ω (If using ferrite bead filters and resistive loads, connect 33 µH in series with a
4-Ω load or 68 µH in series with an 8-Ω load.)
Load Impedance Mono PBTL 2 Ω to 8 Ω (If using ferrite bead filters and resistive loads, connect inductors noted above.)
To change to LC filters instead of ferrite bead filters, remove ferrite beads FB1-4, and
install 22 µH at L1-4 and 0.68 µF 5% X7R 50 V at C23, C25, C27, and C29
Output Power BTL 15 W per channel
Output Power PBTL 30 W
