TPA751DR Mono differential input, Class AB audio amplifier with effective low-level shutdown

Explanation   The TPA751 is a bridged load (BTL) audio power amplifier, especially for applications requiring low-voltage internal speakers for development. Powered by a 3.3-V power supply, the TPA751 can provide continuous output power of 8,250 MW down line—less than 0.6% THD + N load across the entire audio tape. Although this device is characterized by output up to 20 kHz, its operation has been optimized for applications such as wireless communication in narrowband bands. The BTL configuration eliminates most applications on external coupling capacitors, which is especially important for devices powered by small batteries. The device adopts an application-sensitive turn-off mode that is sensitive to current power supply.   Characteristics   Fully meets the specified 3.3-V and 5-V operating conditions Wide power supply compatibility of 2.5V - 5.5V The power supply voltage is suppressed at 217 Hz 84 V decibel deputy station = 5 volts 81 V decibels for the deputy director is 3.3 V The output power is R L, with a milliwatt sub-director of 8,700 V = 5 volts The 250 volt mwa sub-station is 3.3 V Ultra-low power shut-off mode current... 1.5 nA Thermal and short-circuit protection Surface mount packaging SOIC packaging Adopt MSOP for PowerPAD™ MSI Youth ™ (BGA) packaging
