TPA701 - Texas Instruments

TPA701 700-mW MONO LOW-VOLTAGE AUDIO POWER AMPLIFIER

The TPA701 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 TPA701 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 kH.

Features

a shutdown mode for power-sensitive applications with a supply current of 1.5 nA during shutdown. The TPA701 is available in an 8-pin SOIC surface-mount package and the surface-mount PowerPAD MSOP, which reduces board space by 50% and height by 40%. Audio Input RF RI CI CB From System Control 4 IN
