ESS ES6603S** is a high-performance audio amplifier IC designed for use in car audio systems and other audio applications.

The ESS ES6603S is a high-performance audio amplifier IC designed for use in car audio systems and other audio applications. Below are the factual specifications, descriptions, and features:

Manufacturer: ESS Technology, Inc.

Part Number: ES6603S

Specifications:

  • Type: Class D Audio Power Amplifier
  • Output Power:
  • Up to 50W per channel (4Ω, 14.4V, 10% THD+N)
  • Up to 75W per channel (2Ω, 14.4V, 10% THD+N)
  • Supply Voltage Range: 6V to 18V (operational)
  • Efficiency: >90% (typical for Class D operation)
  • Total Harmonic Distortion + Noise (THD+N): <0.1% (typical at 1W, 4Ω)
  • Signal-to-Noise Ratio (SNR): >100dB (A-weighted)
  • Operating Temperature Range: -40°C to +85°C

Descriptions:

  • The ES6603S is a monolithic Class D amplifier optimized for automotive audio applications.
  • It integrates PWM modulation, gate drivers, and protection circuits for reliable performance.
  • Designed for bridge-tied load (BTL) configurations, delivering high power with minimal heat dissipation.
  • Suitable for subwoofers, midrange, and full-range speaker systems in car audio setups.

Features:

  • High-Efficiency Class D Operation (reduces power loss and heat generation).
  • Integrated Fault Protection (overcurrent, overtemperature, undervoltage lockout).
  • Low EMI Emission (compatible with automotive EMC standards).
  • Standby Mode (low quiescent current for power savings).
  • Single-Supply Operation (simplifies power supply design).
  • Compact Package (suitable for space-constrained applications).

This information is based on ESS Technology's official documentation for the ES6603S IC. For detailed application notes and schematics, refer to the manufacturer's datasheet.
