Overview
CD7379CZ is a 13W×4 four-channel audio power amplifier circuit, which is mainly used as a dual One-channel (dual BTL), three-channel (single BTL + two-channel) or four-channel audio power amplification. Its characteristics are as follows:

● Strong load capacity: 2×38W (dual BTL, VCC=18V, f=1kHz, THD=10%, RL=4Ω)
                                  4×11W (per channel, VCC=18V, f=1kHz, THD=10%, RL=4Ω)
                                  2×20W (dual BTL, VCC=18V, f=1kHz, THD=10%, RL=8Ω)
                                  4×13W (per channel, VCC=15V, f=1kHz, THD=10%, RL=2Ω)
● The internal gain is fixed (AV =26dB / BTL), and the peripheral circuit is extremely simple
● Excellent ST-BY function (compatible with CMOS)
● The "poof" sound is small when starting up
● Over power voltage protection function
● Load short circuit protection function
● Overheat protection function
● Package form: FZIP15
