LTK5128 Detail Informations

Part Number : LTK5128 Function : 5W AB / D Audio Power Amplifier Package  : ESOP-8 type Manufacturers : LTKCHIP TECHNOLOGY Image ltk5128-audio-power-amplifier-chip Description The LTK5128 is a 5W, mono Class AB / Class D operating mode cut Function, ultra-low EMI, no need to filter the audio power amplifier chip. LTK5128 through a MODE pin can easily switch to AB class Mode, completely eliminate EMI interference. Operating voltage 2.5V-5.5V, in Class D Amplifier mode can provide more than 90% efficiency, the new filter-free Wave structure can save the traditional Class D amplifier output low-pass filter, Thus saving the system cost and PCB space, is ideal for portable applications select. LTK5128 using a unique DRC (Dynamic range control) Technology, reducing the high-power output, due to the loss of the waveform cut to bring the top True, compared to similar products, dynamic response is even better.   Pinout ltk5128-datasheet-pinout   Features 1. Filterless Class D / Class AB amplifiers with low quiescent current sum Low EMI 2. FM mode without interference 3. Excellent blasting sound suppression circuit 4. Low noise, low distortion 5. DRC dynamic distortion correction circuit 6.  10% THD + N, VDD = 5V, 4Ω load, provided Up to 3W of output power 7. 10% THD + N, VDD = 5V, 2Ω load, provided Up to 5W of output power 8. Short-circuit current protection 9. Undervoltage protection 10. Shutdown current <0.5uA Application Circuit ltk5128-application-circuit
