TPF632C-TR

The 3PEAK TPF632C/605C/607C are 3-VRMS popfree stereo line drivers with the integrated charge pump generating the negative supply rail which allows the removal of the output DC-blocking capacitors. The devices are capable of driving 3-VRMS into a 2.5kΩ load with single 5V supply voltage. The TPF632C has differential inputs, the TPF605C/607C support single-ended inputs, and all can use external resistors for flexible gain setting. The 3PEAK TPF632C/605C/607C has built-in enable/shutdown control for pop-free on/off control. The TPF632C/605C has an external under-voltage detector that mutes the output when monitored voltage drop below set value. Using the TPF632C/605C/607C 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 traditional op-amp requires a split-rail power supply to achieve same. The device is ideal for single-supply electronics where size and cost are critical design parameters.
