Design Notes

  • Proper heat sinking is required for the external output stage transistors in high-power designs
  • Use symmetric PCB layout to minimize distortion and maintain signal integrity
  • Power supply decoupling is critical to avoid oscillation at high frequencies
  • Ensure correct biasing of the output stage to reduce crossover distortion
  • Overcurrent protection should be validated with real load conditions

How to Choose This Part

  • Select for medium-to-high power audio amplifier designs (50W to 80W range)
  • Suitable for applications requiring low distortion and wide bandwidth
  • Ideal when integrating driver and protection circuits in a single IC
  • Consider for designs using discrete output transistors

Applications

  • Home audio HiFi systems
  • Audio amplifiers and receivers
  • Professional sound equipment
  • Multimedia speaker systems

Alternative / Equivalent Products

  • UPC1297V
  • TA7317P
  • LM4702
  • STK amplifier modules (integrated alternatives)

CV203 datasheet

Description

The CV203 is Car radio audio amplifier.

The TDA2003 has improved performance with the same pin configuration as the TDA2002. The additional features of TDA 2002, very low number of external components, ease of assembly, space and cost saving, are maintained. The device provides a high output current capability (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to protection against DC and AC short circuit between all pins and ground, thermal over-range, load dump voltage surge up to 40V and fortuitous open ground.

Pin Configuration (TO-220-5)

  • Pin 1: Non-inverting input (+)
  • Pin 2: Inverting input (−)
  • Pin 3: Ground
  • Pin 4: Output
  • Pin 5: Supply voltage (VS)

Key Features

  • High output current capability: up to 3.5A
  • Low harmonic distortion
  • Low crossover distortion
  • Wide supply voltage range (typically 8V–18V, up to 28V absolute max)
  • Low external component count
  • Same pinout as TDA2002 (drop-in replacement)

Applications

  • Car audio amplifiers
  • Portable speakers
  • TV audio output stages
  • DIY audio amplifier projects
  • Alarm and announcement systems
