描述 Description

The LX1708 is a fully integrated stereo class-D CMOS audio amplifier optimized for highly efficient operation and minimum system cost. The stereo BTL (Bridge-tied-load) configuration uses 3-level PWM modulation. This allows eliminating the LC filter to reduce the system cost and simplify the system design. The LX1708 outputs 15W into each of two channels with better than 85% efficiency. The entire signal path from input to output is differential to reject any sources of common-mode noise or distortion. The part features on–board H-bridge output stages with low RDSON. External bootstrap capacitors are all that is required to provide the gate drive to the all-NFET output stage since on-board bootstrap diodes are provided. The LX1708 also features Mute and Standby modes, POP-free turn-on and turn-off, under-voltage lockout for both input supplies, and multi-level over temperature protection. The LX1708 is offered in a small thermally efficient footprint, low profile surface mountable 32-pin Micro Lead Quad Package (MLPQ) in 7mm x 7mm.  ROHS, PB Free-->  ROHS
