TPA3122D2: Square signal as Vin

Other Parts Discussed in Thread: TPA3122D2

Hi!! I have two questions about TPA3122D2:

-First: Can I get an output bipolar simetrical voltage (i.e. -5V to +5V) if I introduce at pin LIN a square bipolar signal (i.e. -500mV to +500mV) using the schematic of figure 28 from datasheet? In my case the load is a resistor of 1kohm because I'm not using this C.I. to audio application and power supply is +12V.TPA

-Second: How can I get an output more than 80V using a TPA3122D2? or is necessary change the C.I.?

Thanks.
