Product Overview

The TPA2005D1DGN is a 1.4W Mono Class-D Audio Amplifier that requires only three external components. This high efficiency filter-free audio power amplifier features 84% efficiency, -71dB PSRR at 217Hz, improved RF rectification immunity and 15mm² total PCB area that makes the TPA2005D1 ideal for cellular handsets. A fast start-up time of 9ms with minimal pop makes it ideal for PDA applications. In cellular handsets, the earpiece, speaker phone and melody ringer can each be driven by the TPA2005D1. The device allows independent gain control by summing the signals from each function while minimizing noise to only 48µVRMS. This amplifier has short-circuit and thermal protection.
  • 1.4W into 8R from a 5V supply at THD = 10% (typical)
  • Maximum battery life and minimum heat
  • Capable of driving an 8R speaker (2.5V <=VDD <=5.5V) and a 4R speaker (2.5V <= VDD <= 4.2V)
  • Optimized PWM output stage eliminates LC output filter
  • Internally generated 250kHz switching frequency eliminates capacitor and resistor
  • Improved PSRR and wide supply voltage (2.5 to 5.5V) eliminates need for a voltage regulator
  • Fully differential design reduces RF rectification and eliminates bypass capacitor
  • Improved CMRR eliminates two input coupling capacitors
  • Green product and no Sb/Br

Applications

Wireless, Communications & Networking, Audio

Warnings

This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
