概述

The 3PEAK TPF632A/605A/607A are 3-V_RMS pop-free 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 2.5-kΩ load with single 5V supply voltage. The TPF632A has differential inputs, the TPF605A/607A support single-ended inputs, and all can use external resistors for flexible gain setting.

The 3PEAK TPF632A/605A/607A has built-in enable/shutdown control for pop-free on/off control. The TPF632A/605A has an external under-voltage detector that mutes the output when monitored voltage drop below set value. Using the TPF632A/605A/607A in audio products can reduce component count considerably compared to traditional methods of generating a 3-V_RMS 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.
