TPA6020A2 - 2.8-W STEREO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER

General Description

The TPA6020A2 is a 2.8-W stereo bridge-tied load (BTL) amplifier designed to drive stereo speakers with at least 3-Ω impedance.

The device operates from 2.5 V to 5.5 V, drawing only 8 mA of quiescent supply current.

Key Features

  • Ideal for Notebook PCs.
  • Fully Differential Architecture and High PSRR (-80 dB) Provide Excellent RF Rectification Immunity.
  • 2.8 W Into 3 Ω From a 5-V Supply at THD = 10% (Typical).
  • Very Low Crosstalk:.
  • -100 dB Typical at 5 V, 3 Ω.
  • 2.5-V to 5.5-V Operating Range.
  • Low Supply Current:.
  • 8 mA Typical at 5 V.
  • Shutdown Current: 80-nA Typical.
  • Fast Startup (27 ms) With Minimal Pop.
  • Internal Feedback Resis.
