THS7002 EVM Performance
1-15
General Information
Figure 1–10 shows the typical frequency response and Figure 1–11 shows the
typical phase response of the THS7002 EVM preamplifiers + PGAs. This data
was collected with the preamplifiers directly driving the PGA inputs. The PGA
was set to a gain of +2 dB. Typical –3 dB bandwidth is 65 MHz with a ±5-V
power supply and 70 MHz with a ±15-V power supply.
