Manufacturer: Texas Instruments

Overview: TPA321 .ti. SLOS312C – JUNE 2000 – REVISED JUNE 2004 350-mW MONO AUDIO POWER AMPLIFIER WITH DIFFERENTIAL INPUTS • Fully Specified for 3.3-V and 5-V Operation • Wide Power Supply patibility 2.5 V – 5.5 V • Output Power for RL = 8 Ω – 350 mW at VDD = 5 V – 250 mW at VDD = 3.3 V • Ultralow Supply Current in Shutdown Mode . . . 0.

General Description

The TPA321 is a bridge-tied load (BTL) audio power amplifier developed especially for low-voltage applications where internal speakers are required.

Operating with a 3.3-V supply, the TPA321 can deliver 250 mW of continuous power into a BTL 8-Ω load at less than 1% THD+N throughout voice band frequencies.

Although this device is characterized out to 20 kHz, its operation was optimized for narrower band applications such as cellular munications.

Key Features
