TDA7415CB

TDA7415CB is a dual-channel audio power amplifier IC from STMicroelectronics (TDA family). It is designed to drive loudspeakers in compact audio systems such as car radios, head units, and small hi‑fi/back‑speaker applications.
Key points:
- Dual power amplifier with protections (short-circuit, thermal shutdown, undervoltage) and often mute/standby control for quiet startup.
- Suitable for single-supply operation (typical car‑battery voltages); commonly used with 4 Ω to 8 Ω speaker loads.
- Integrated features aim to simplify external circuitry and improve reliability in automotive and consumer audio.
CB suffix indicates a specific package/pinout variant; exact electrical characteristics (output power, quiescent current, gain, operating voltage range) depend on the revision and package. For precise specs, layouts, and application notes, consult the STMicroelectronics datasheet for the TDA7415CB variant.

There isn’t a direct one-to-one equivalent for the TDA7415CB across vendors. Closest substitutes are other dual/quad audio power amplifiers with similar voltage/power, but pinouts and features differ (examples: NXP/TDA7850 family, ST’s TDA7560/TDA7566, or TDA7374/TDA7375 depending on output). For a guaranteed cross-reference, provide the package and required output specs and I’ll suggest exact replacements.

Key features of TDA7415CB:
- Dual-channel audio power amplifier with Bridge-Tied Load (BTL) outputs
- Pop-free mute/standby control for quiet power-on
- Built-in protections: thermal shutdown, short-circuit protection, and undervoltage protection
- Low quiescent current and low distortion for efficient operation
- Robust output protection against load faults (short to GND/Vcc)
- Suitable for compact boards and automotive/portable audio applications
- CB suffix indicates an 8-pin package variant (compact package)
(Please note: for exact electrical specs (power, voltages, gains), consult the official datasheet.)

- Pin count: 16 pins (SO-16/DIP-16 variants).
- Function: Dual audio power amplifier (two-channel/stereo) IC used to drive speakers in consumer or automotive audio applications.
