Applications
The 3PEAK INCORPORATED TPF603/605/607 are
3-VRMS 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-kload 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 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.

3-VRMS Audio Line Driver with Integrated Charge Pump
 
Figure 3 Typical Application Circuit of TPF605Leftand TPF607Right
Typical application circuits are shown as above. TPF603/605/607 operates from a single supply voltage PVDD. It
integrated charge pump generates a negative supply –PVDD at the PVSS pin. The Line driving amplifiers work with
dual supplies: PVDD and –PVDD. Therefore, the DC level of the audio output can be designed to be 0V. A
DC-blocking capacitor typically seen in a single-supplied driver is not necessary.
The supply range of the TPF603/605/607 is 2.7V to 5.5V. For a 3VRMS output, the recommended supply voltage is 5V.
For a 2VRMS output, the recommended supply voltage is 3.3V.
RIN of 2.5kand RFB of 5kset the inverting gain of 2. Because of the exceptional noise performance of
TPF603/605/607, the dominant noise source is actually from RIN. To get better noise performance, lower input
resistance and feedback resistance may be used.
Integrated Charge Pump
The integrated charge pump in TPF603/605/607 generates negative power supply from a single supply PVDD. A flying
capacitor for the charge pump shall be applied between CP and CN. At the same time a decoupling capacitor shall be
applied between PVSS and ground. Typical value for the flying capacitor is 1uF. Typical value of the decoupling
capacitor shall be same as or larger than that of the flying capacitor. Low-ESR capacitors are recommended for the
flying capacitor and the decoupling capacitor.
Audio Signal Amplification Gain Setting
The main application of the TPF603/605/607 is to amplify/buffer audio signals and drive audio lines with very low
distortion. Typical application circuits with inverting gain are shown in Figure. 4.
Non-inverting amplification of audio signals is also possible with same low distortion.
