TDA7057AQ** is a **mono BTL (Bridge-Tied Load) audio power amplifier** manufactured by **Philips (PHI)**.

The TDA7057AQ is a mono BTL (Bridge-Tied Load) audio power amplifier manufactured by Philips (PHI).

Key Specifications:

  • Supply Voltage (VP): 4.5V to 18V
  • Output Power (Po):
  • 8W into 8Ω (at 16V, THD = 10%)
  • 6W into 8Ω (at 12V, THD = 10%)
  • 1.1W into 8Ω (at 6V, THD = 10%)
  • Gain (Gv): Fixed at 40dB (internally set)
  • Total Harmonic Distortion (THD): <0.5% (typical)
  • Quiescent Current (Iq): ~4mA (typical)
  • Input Resistance (Rin): ~100kΩ
  • Operating Temperature Range: -40°C to +85°C
  • Package: DBS9P (9-pin SIL plastic package)

Descriptions & Features:

  • Mono BTL Output: Eliminates the need for an output coupling capacitor.
  • No External Components Required: Minimal external circuitry needed (only input coupling capacitor and supply decoupling capacitor).
  • Mute Function: Controlled via a DC voltage on Pin 3 (MUTE).
  • Thermal Protection: Built-in thermal shutdown to prevent overheating.
  • Short-Circuit Proof: Protected against short circuits at the output.
  • Low Standby Current: Suitable for battery-powered applications.
  • Wide Supply Voltage Range: Operates from 4.5V to 18V, making it versatile for various applications.

This IC is commonly used in portable audio devices, TVs, radios, and other consumer electronics requiring a compact, efficient mono amplifier.
