General Description

BD27400GUL is a low voltage drive class-D monaural speaker amplifier that was developed for cellular telephones, mobile audio products and the others.

The LC filter of the speaker output is unnecessary and the external part can compose a speaker amplifier at three.

Because the efficiency is high and is low consumption power with the class-D operation, it is the optimal for the application of the battery drive.

Key Features

  • High output power 2.5W typ. (VDD=5V, RL=4Ω, THD+N=10%, BTL）.
  • Very small package 9-Pin WL-CSP.
  • Gain selectable by external resistor.
  • LC Filter less.
  • Protection circuitry (Short protection, Thermal shutdown, Under voltage lockout).
  • Analogue differential input / PWM digital output.
  • Pop noise suppression circuitry VCSP50L1.
