Default FS: IRAUDAMP1 Rev. 4.1 Eval Board

I only used this board for a short time to test it, but let me say it sounds fantastic. I was shocked by the lack of a noise floor. I couldn't even tell it was on with my ear pressed against the tweeter. This was a huge surprise after living with the "Tripath Hiss™" for so long.

Price is $200 w/ free shipping within North America. Other countries please ask for a shipping quote. PayPal preferred.

Features:

- Complete Analog Input Class D Audio Power Amplifier
- 500W + 500W Peak Stereo (2CH) Output
- THD+N=0.008% @1kHz, 100W, 4-Ohm
- High Efficiency 93% @350W, 1kHz, 4-Ohm
- Simple Self Oscillating Half-Bridge Topology
- Includes all Local House-keeping Power Supplies
- Protection Functions
- Wide Operating Supply Voltage Range +/-25v~60v
- Immune to Power Supply Fluctuations

Description:

The IRAUDAMP1 is an example of a complete class D audio power amplifier design using the IR2011S, high speed high voltage gate driver IC. The design contains protection functions and house keeping power supplies for ease of use. This reference design is intended to demonstrate how to use the IR2011S, implement protection circuits, and design an optimum PCB layout.
