The devices are capable of driving 3-VRMS into a 2.5-kΩ load with single 5V supply voltage. The TPF603 has differential inputs, the TPF605/607 support single-ended inputs, and all can use external resistors for flexible gain setting. The TPF603/605/607 has built-in enable/shutdown control for pop-free on/off control. The TPF603/605 have an external under-voltage detector that mutes the output when monitored voltage drop below set value. Using the TPF603/605/607 in audio products can reduce component count considerably compared to traditional methods of generating a 3-VRMS output. The device needs only a single 5V supply to generate 8.5-VPP output while tradit...
