.ti. SLOS697A - AUGUST 2011 - REVISED OCTOBER 2012 3.2 W Mono Class-D Audio Power Amplifier With Selectable Gain and Auto-Recovering Short-Circuit Protection Check for Samples: TPA2038D1 Features - Filter-Free Mono Class-D Speaker Amp - GAIN Pin Selects Between 6 d B and 12 d B - 3.2 W into 4 Ω from 5 V supply at 10% THD+N - Powerful Mono Class-D Speaker Amplifier - 1% at 1.4 W into 8 Ω from 5 V Supply - 1% at 2.5 W into 4 Ω from 5 V Supply - Integrated Image Reject Filter for DAC Noise Reduction - Low Output Noise of 20 μV - Low Quiescent Current of 1.5 m A - Auto-Recovering Short-Circuit Protection - Thermal-Overload Protection - 9-Ball 1,21 mm × 1,16 mm 0,4 mm Pitch WCSP APPLICATIONS - Wireless or Cellular Handsets and PDAs - Portable Navigation Devices - General Portable Audio Devices DESCRIPTION The TPA2038D1 is a 3.2 W into 4-ohm (10% THD) high efficiency filter-free class-D audio power amplifier. The GAIN pin sets gain to either 6 d B or 12 d B. Features like 95% efficiency, 1.5 m A quiescent current, 0.5 μA shutdown current, 81 d B PSRR, 20 μV output noise, and improved RF immunity make the TPA2038D1 class-D amplifier ideal for cellular handsets. A start-up time is within 4 ms with no turnon pop. The TPA2038D1 is available in a 1.21 mm x 1.16 mm, 0.4 mm pitch wafer chip scale package (WCSP). APPLICATION CIRCUIT GAIN Gain...
