TEA2028A** is a monolithic integrated circuit manufactured by **STMicroelectronics (ST)**.

The TEA2028A is a monolithic integrated circuit manufactured by STMicroelectronics (ST). It is designed as a dual power amplifier for portable audio applications.

Specifications:

  • Supply Voltage (VCC): 3V to 12V
  • Output Power:
  • 1.1W per channel (THD = 10%, RL = 4Ω, VCC = 6V)
  • 2.3W per channel (THD = 10%, RL = 4Ω, VCC = 9V)
  • Total Harmonic Distortion (THD): Typically 0.5% (at 1W, RL = 4Ω, f = 1kHz)
  • Quiescent Current: 9mA (typical)
  • Operating Temperature Range: -40°C to +85°C
  • Package: DIP-16 or SO-16

Descriptions:

  • Dual-channel audio amplifier with built-in thermal protection.
  • Low quiescent current makes it suitable for battery-powered devices.
  • Requires minimal external components for operation.
  • Includes mute and standby functions for power saving.

Features:

  • Dual Bridge Configuration: Allows operation without output coupling capacitors.
  • Low Noise Preamplifier: Includes an internal preamp stage.
  • Short-Circuit Protection: Built-in safeguards against output shorts.
  • Wide Supply Voltage Range: Supports operation from 3V to 12V.
  • Thermal Shutdown: Protects the IC from overheating.

This IC is commonly used in portable radios, cassette players, and other small audio devices.
