1.10 THS4012 EVM Performance

Figure 1–6 shows the typical frequency response of the THS4012 EVM using
the noninverting configuration (G = 2). Typical – 0.1 dB bandwidth is 25 MHz
and – 3-dB bandwidth is 75 MHz with both a

±

15-V power supply and a

±

5-V

power supply.

Figure 1–7 shows the typical phase response of the THS4012 EVM using the
noninverting configuration (G = 2). This shows a 75

°

phase margin for both

±

15-V and

±

5-V power supplies on both channels.
