IT2012 - 2.5W/CH Stereo Filter-free Class-D Audio Power Amplifier


The IT2012 is a high efficiency stereo filter-free class-D audio amplifier which can deliver maximum 2.5W/CH RMS power to 4Ω load with 5.5V supply in a Bridge Tied Load (BTL) configuration.

The IT2012 features independent shutdown controls for each channel. The gain can be selected to 6, 12, 18, or 24dB utilizing the G0 and G1 gain select pins. Fully differential design eliminates two input coupling capacitors and provides increased immunity to noise.

The IT2012 contains Over Current and Over Temperature Protection, preventing IT2012 from damages of short current and overheating. It also features good THD+N and self gain-adjusting depop scheme, achieving high sound quality.

The high performance, low cost characteristics make IT2012 well suitable for cellular phones, portable electronic devices, PDAs, smart phones and portable computers.
