TDA7275 is a monolithic integrated circuit manufactured by STMicroelectronics (ST).

The TDA7275 is a monolithic integrated circuit manufactured by STMicroelectronics (ST). Below are its specifications, descriptions, and features:

Specifications:

  • Manufacturer: STMicroelectronics (ST)
  • Type: Audio Amplifier IC
  • Operating Voltage Range: 3V to 12V
  • Output Power: 1W (typical at 9V supply, 8Ω load)
  • Quiescent Current: 9mA (typical)
  • Total Harmonic Distortion (THD): 0.5% (typical at 1W output)
  • Gain: 39dB (fixed)
  • Package: DIP-8 or SO-8

Descriptions:

The TDA7275 is a low-voltage audio power amplifier designed for portable audio applications. It provides a fixed gain of 39dB and delivers up to 1W of output power with low distortion. The IC is suitable for battery-powered devices such as radios, portable speakers, and intercom systems due to its low quiescent current and wide operating voltage range.

Features:

  • Low quiescent current (9mA typical)
  • No external components required for operation (fixed gain)
  • Short-circuit and thermal protection
  • Low distortion (0.5% THD at 1W)
  • Wide supply voltage range (3V to 12V)
  • Compact DIP-8 or SO-8 package

This information is strictly factual and based on the manufacturer's datasheet.
