TPA301DGNR Description

Short technical summary and product information.

The TPA301DGNR from Texas Instruments is a bridge-tied load (BTL) audio power amplifier specifically developed for low-voltage applications requiring internal speakers. Operating with a 3.3-V supply, it can deliver 250-mW of continuous power into an 8-Ω BTL load at less than 1% THD+N throughout voice band frequencies. Although characterized up to 20 kHz, its operation is optimized for narrower band applications like cellular communications.

 

This amplifier supports a wide power supply range from 2.5 V to 5.5 V. At 5 V, it can output 350 mW into an 8-Ω load. The BTL configuration eliminates the need for external coupling capacitors on the output, which is beneficial for small, battery-powered equipment. It also features a shutdown mode for power-sensitive applications, with a quiescent current of only 0.15 µA during shutdown.

 

The TPA301DGNR is available in an 8-pin HVSSOP surface-mount package. It operates within an ambient temperature range of -40°C to 85°C and has a lead finish/ball material of NiPdAu. The device is RoHS and REACH unaffected.
