ft2705

ft2705 2X10W Class-D Stereo Audio Power Amplifier with Automatic Level Control GENERAL DESCRIPTION The ft2705 is a highly efficient 2X10W Class-D stereo audio power amplifier with automatic level control (ALC). It operates with a wide range of supply voltages from 4.5V to 8.8V in either dual bridge-tied-load (BTL) or parallel bridge-tied-load (PBTL) configuration. With a supply voltage at 8.8V, the ft2705 can deliver 10W per channel into a pair of 4Ω speakers in dual BTL configuration (stereo mode), or 14W into a single 3Ω speaker in PBTL configuration (mono mode), with 10% THD+N. The ft2705 features ALC to constantly monitor and safeguard the audio outputs against the supply voltage, preventing output clipping distortion, excessive power dissipation, or speaker over-load. Once an over-level condition is detected in either channel, the ALC lowers the voltage gain of both audio amplifiers together to eliminate output clipping distortion while maintaining a maximum dynamic range of th...
