PT2332 - Princeton Technology

PT2332 2.2W x 2 Class-D Audio Power Amplifier

The PT2332 is a CLASS-D power amplifier designed for audio equipments, maximum output power can reach up to 2.2W x 2 (VDD = 5V, RL = 4Ω, THD = 10%). The PT2332 composed of exclusively designed CLASS-D circuitry (patented) by PTC, along with the most advanced semi-conductor technology. When compared to the traditional CLASS-AB amplifiers, the PT2332’s has a m.
