TDA7491HV Datasheet 20 W + 20 W Dual Btl Class-d Audio Amplifier

Manufacturer: STMicroelectronics

Overview: TDA7491HV Datasheet 20 W + 20 W dual BTL class-D audio amplifier PowerSSO-36 exposed pad up PowerSSO-36 with exposed pad.

General Description

The TDA7491HV is a dual BTL class-D audio amplifier with single power supply designed for LCD TVs and monitors.

Thanks to the high efficiency and exposed-pad-up (EPU) and down (EPD) packages, no separate heatsink is required.

The TDA7491HV is pin-to-pin compatible with the TDA7491P and TDA7491LP.

Key Features

  • 20 W + 20 W continuous output power:.
  • RL = 8 Ω, THD = 10% at VCC = 18 V.
  • Wide-range single-supply operation (5 - 18 V).
  • High efficiency (η = 90%).
  • Four selectable, fixed gain settings of nominally 20 dB, 26 dB, 30 dB and 32 dB.
  • Differential input minimize common-mode noise.
  • No ‘pop’ at turn-on/off.
  • Standby and mute features.
  • Short-circuit protection.
  • Thermal overload protection.
  • External synchroni.
