Video Performance
The color bar signal in Figure 3 shows excellent amplitude characteristics and no attenuation of colors with
respect to the luminance signal.
∆: 2.02V
@: 30.0mV

The CCIR330/5 test pattern requires one of the greatest dynamic ranges, and therefore tests the OPA361-Q1
output voltage swing capability. The scope plot shown in Figure 4 has been taken with a 2.8V supply and shows
no clipping on the top side of the signal.
∆: 2.30V
@: 2.31mV

The multiburst test patterns have different sine-wave burst sections with the following frequencies: 0.5MHz,
1MHz, 2MHz, 4MHz, 4.8MHz and 5.8MHz with 420mVPP. There is no visible attenuation even at the highest
frequencies, which indicates a very flat frequency response of the OPA361-Q1. As shown in Figure 5 and
Figure 6, the top line illustrates the full signal and the bottom line is a more detailed view of the last three sine
wave bursts.
