TDA7493 - 3-watt + 3-watt dual BTL class-D audio amplifier

General Description

The TDA7493 is a dual BTL class-D audio amplifier, specially designed for LCD TV, LCD monitors or small speakers on cradles with single-supply operation.

The filterless operation allows the external component count to be reduced.

The TDA7493 is assembled in the HTSSOP24 package.

Key Features

  • 3.0 W + 3.0 W of continuous output power with RL = 4 Ω, THD = 10%, VCC = 5 V (filterless).
  • 2.8 W + 2.8 W of continuous output power with RL = 4 Ω, THD = 10%, VCC = 5 V (with filter).
  • Single supply voltage range 3.0 V to 5.5 V.
  • High efficiency (η = 83%).
  • Four selectable, fixed gain settings of 6 dB, 12 dB, 15.6 dB and 18 dB.
  • Differential inputs minimize common-mode noise.
  • Filterless operation.
  • Standby feature.
  • Short.
