General Description

The L-1000 is a single chip digital audio amplifier Module. Including power stage for stereo amplifier system. The L-1000 is integrated with versatile digital audio signal processing functions, ADC functions, high-performance, high-fidelity Fully digital PWM modulator and two high-power full-bridge MOSFET Power stages. The L-1000 receives digital serial audio Data with sampling frequency from 8KHZ through 96KHZ. It delivers 2 x 30 watts in stereo mode without heat sink. The L-1000 has a mixer and Bi-Quad filters which can Be used to implement the essential audio signal processing Functions like loudness control, compensation of a loud Speaker response and parametric equalization. All the functions of the L-1000 can be controlled by internal Register values from MCU via I2C host interface bus.
