TPA2014D1RGPR

The Texas Instruments TPA2014D1RGPR is a high-efficiency Class-D audio power amplifier featuring an integrated boost converter. This device is capable of driving up to 1.5 W into an 8 Ω speaker from a 3.6 V supply, with a typical efficiency of 85%, contributing to extended battery life in portable applications.

Key electrical specifications include an analog input type and a Class-D boosted architecture. It supports a wide operating supply voltage range from 2.5 V to 5.5 V for both analog and power stage supplies. The amplifier offers three selectable gain settings: 2 V/V, 6 V/V, and 10 V/V. It maintains a low Total Harmonic Distortion plus Noise (THD+N) of 1% at 1 kHz when driving an 8 Ω load.

The TPA2014D1RGPR operates within an environmental temperature range of -40°C to 85°C. It is available in DSBGA (YZH) and VQFN (RGP) surface-mount packages. The DSBGA package measures 5.0625 mm², while the VQFN package is 16 mm² (4 mm x 4 mm). Features such as independent shutdown for the boost converter and Class-D amplifier, differential inputs to reduce RF common noise, and built-in input low-pass filters enhance its performance in noisy environments.

Applications for the TPA2014D1RGPR include cell phones, PDAs, GPS devices, and other portable electronics where efficient audio amplification is required.
