Description

The STK412-430 series are class H audio power amplifier hybrid ICs that feature a built-in shift power  upply circuit. These Provide ICs high efficiency audio power amplification by controlling (switching) the supply voltage supplied to the power transistors according to the detected level of the input audio signal.

1. Pin compatible IC series that covers power ratings from 50 W × 2 channels to 180 W × 2 channels at 0.7 or 0.8% THD, 20 Hz to 20 kHz. This allows the use of a common PCB for all output classes.

2.  The pin arrangement is also unified with that of the three-channel STK413-000 series. This means that PCBs designed for three-channel models can also be used for two-channel models.

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

Alternative Devices

  • TDA2002 (lower power predecessor)
  • TDA2030 (higher power, dual supply capable)
  • LM1875 (hi-fi class alternative)
  • TDA2050 (higher output power)
