Description
The TDA7050T is a low-voltage, mono BTL (Bridge-Tied Load) audio power amplifier from NXP Semiconductors. Designed for portable devices, it operates at 1.6V to 6V, delivering 1W output (4Ω, 6V, 10% THD).
### Key Features:
- BTL configuration (no output coupling capacitor needed).
- Low power consumption (ideal for battery-powered devices).
- Minimal external components (simple design).
- Thermal protection & short-circuit proof.
- Volume control via DC voltage (pin 2).
### Applications:
- Portable radios, toys, and small audio devices.
- Headphone amplifiers (with external resistors).
### Pinout (5-pin TO-220/SOT110):
1. Input (non-inverting)
2. Volume control
3. GND
4. Output+
5. Output-
Compact and efficient, the TDA7050T is a cost-effective solution for low-power audio amplification.
