        1 Features 3 Description
        1 The TPA2025D1 is a high efficiency Class-D audio • Built-In Enhanced Battery Tracking Automatic
        power amplifier with battery tracking AGC technology Gain Control (AGC) and an integrated Class-G boost converter that
        – Limits Battery Current Consumption enhances efficiency at low output power. It drives up
        • 1.9 W into 8-Ω Load from 3.6-V Supply (1% to 1.9 W into an 8-Ω speaker (1% THD+N). With 85%
        THD+N) typical efficiency, the TPA2025D1 helps extend
        battery life when playing audio. • Integrated Adaptive Boost Converter
        – Increases Efficiency at Low Output Power The built-in boost converter generates a 5.75-V
        supply voltage for the Class-D amplifier. This • Low Quiescent Current of 2 mA From 3.6 V
        provides a louder audio output than a stand-alone
        • Thermal and Short-Circuit Protection With Auto amplifier directly connected to the battery. The battery
        Recovery tracking AGC adjusts the Class-D gain to limit battery
        • 20-dB Fixed Gain current at lower battery voltage.
        • Similar Performance to TPA2015D1 The TPA2025D1 has an integrated low-pass filter to
