GPY0031A中文资料2.0W Audio Power Amplifier数据手册Generalplus规格书

描述 Description

The GPY0031A (a bridge-tied load (BTL) and GPY0032A (a BTL or singled-ended (SE)), are audio amplifiers, designed especially for low-voltage applications which normally require internal speaker. Operating on 5V power supply, GPY0031A / 32A is able to deliver 2.0W of successive average power into 4Ω load at less than 10% of THD+N throughout voice band frequencies and embedded the de-pop circuit to minimize the turn-on and turn-off pop noise. Normally, it is applied for GPC series, GPF series, GPL series and other GENERALPLUS products. The GPY0031A / 32A are easily to be used in various applications and products.
