Description

The LX1708 is part of a new generation of fully integrated stereo class-D amplifiers from Microsemi.

This CMOS audio amplifier LX1708 is 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 part features onboard 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 onboard bootstrap diodes are provided.The LX1708 also features Mute and Standby modes, over-current protection,POP-free turn-on and turn-off, undervoltage lockout, over-voltage protection, and over-temperature protection.

The LX1708 is offered in a small footprint, low profile surface mountable 32-pin Micro Lead Quad Package (MLPQ) in 7mm x 7 mm.
