This CMOS monolithic class-D amplifier series is optimized for low voltage, low power operation and minimum system cost. The products are ideal for use in battery powered applications where low power consumption is desirable such as cell phones, PDA’s, web tablets and other low power systems. The LX1701 family provides very low quiescent current consumption through the use of a proprietary output modulation scheme. This technology enables filter-less operation in many applications. The part features on board, low Rdson, co...
