The TPA6021A4 is a stereo audio power amplifier that drives 2 W/
channel of continuous RMS power into a 4-Ω load when a heat sink is
used. Advanced BTL (speaker) and SE (headphone) dc volume control
minimizes external components.
Key Features
• 2-W stereo amplifier
• 32-step DC volume control
• 4.5 to 5.5 V
• Depop circuitry
• Packaging: Through-hole DIP
Applications
• Laptops
• Monitors

The TPA505x series of devices provides a cost-effective,
integrated lip-sync solution for TV and home theater
applications. The TPA505x family provides up to 170 ms of delay per
channel and comes in two stereo versions and one four-channel
version. The ease of use and small footprint make this part ideal for
flat-panel TV applications.
