TPA721 700-mW MONO LOW-VOLTAGE AUDIO POWER AMPLIFIER

TPA721 Description

TPA721 www.ti.com SLOS231E * NOVEMBER 1998 * REVISED JUNE 2004 700-mW MONO LOW-VOLTAGE AUDIO POWER AMPLIFIER .
The TPA721 is a bridge-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers are required.

TPA721 Features

* Fully Specified for 3.3-V and 5-V Operation
* Wide Power Supply Compatibility 2.5 V
* 5.5 V
* Output Power for RL = 8 Ω
* 700 mW at VDD = 5 V, BTL
* 250 mW at VDD = 3.3 V, BTL
* Integrated Depop Circuitry
* Thermal and Short-Circuit P

TPA721 Applications

* where internal speakers are required. Operating with a 3.3-V supply, the TPA721 can deliver 250-mW of continuous power into a BTL 8-Ω load at less than 0.6% THD+N throughout voice band frequencies. Although this device is characterized out to 20 kHz, its operation is optimized for narrower band appl
