Description

The DA7202 is a powerful, highly efficient, low EMI Class D speaker driver that can drive 8W into 4Ω loads directly from a 2S Lithium-ion battery pack to power a variety of two-cell portable applications such as Ultrabooks and tablets.

It uses a fully differential switched-mode amplifier architecture with a fixed +18dB gain, with differential analog inputs. It also has a PWM modulator and an H-bridged switched power output stage that delivers 5W (dynamic) into an 8Ω load, making a speaker sound louder on portable devices.

Benefits

  • Low component count
  • Small PCB area due to 9 bump WLCSP 0.5mm pitch package
  • Good PSRR and THD+N
  • Differential audio inputs
  • Low EMI
  • Short circuit and thermal overload protection with auto-recovery
