TPA122 Datasheet 150-mw Stereo Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: .ti. TPA122 SLOS211E – AUGUST 1998 – REVISED JUNE 2004 150-mW STEREO AUDIO POWER.

General Description

The TPA122 is a stereo audio power amplifier packaged in either an 8-pin SOIC, or an 8-pin PowerPAD™ MSOP package capable of delivering 150 mW of continuous RMS power per channel into 8-Ω loads.

Amplifier gain is externally configured by means of two resistors per input channel and does not require external pensation for settings of 1 to 10.

THD+N when driving an 8-Ω load from 5 V is 0.1% at 1 kHz, and less than 2% across the audio band of 20 Hz to 20 kHz.

Key Features

  • 150-mW Stereo Output.
  • PC Power Supply Compatible.
  • Fully Specified for 3.3-V and 5-V Operation.
  • Operation to 2.5 V.
  • Pop Reduction Circuitry.
  • Internal Midrail Generation.
  • Thermal and Short-Circuit Protection.
  • Surface-Mount Packaging.
  • PowerPAD™ MSOP.
  • SOIC.
  • Pin Compatible With LM4880 and LM4881 (SOIC) D OR DGN.
