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 preampl 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.
