The 8 V to 18 V supply range covers the automotive battery envelope from cold-crank dip to alternator overvoltage, but output power scales with rail voltage — at 12 V the 4 Ω stereo output drops to roughly 30 W. The 2 Ω quad configuration is useful for driving multiple small speakers in a distributed system, but the thermal load at 2 Ω per channel is higher than the 4 Ω stereo case. ## Active lifecycle — no LTB pressure for current BOMs The Automotive series designation signals that the device is qualified to ST's automotive-grade flow, which includes extended temperature testing and reliability screening beyond the commercial baseline. ## Depop, standby, and protection — what the feature set buys you The integrated depop circuit suppresses the turn-on thump that otherwise couples into the speakers through the DC-blocking capacitors. Short-circuit and thermal protection latch the output stage off during a fault and auto-recover when the junction cools — no external crowbar or fuse needed. The standby pin pulls the quiescent current to near zero, which matters for ignition-off battery drain in automotive infotainment systems.","metaTitle":"STMicroelectronics E-TDA7375AV Class AB Amp, 43W x 2 @ 4Ω","metaDescription":"STMicroelectronics E-TDA7375AV Class AB audio amplifier, 43W x 2 @ 4Ω or 12W x 4 @ 2Ω, Multiwatt-15, automotive temp range -40°C to 150°C.

The difference is output power: the E-TDA7379 delivers 38 W x 2 at 4 Ω versus the E-TDA7375AV's 43 W x 2 at 4 Ω. The pinout and supply range are identical, so a board designed for the E-TDA7379 will accept the E-TDA7375AV without layout changes, but the higher output of the E-TDA7375AV may require a larger heatsink or better PCB thermal management."},{"question":"What compliance documentation does STMicroelectronics provide for E-TDA7375AV?","answer":"The E-TDA7375AV is certified ROHS3 compliant, meeting the EU Restriction of Hazardous Substances directive.
