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.
