... Package Type θ JA 20-Lead QSOP 83 Maximum Power Dissipation The maximum safe power dissipation in the ADA4412-3 package is limited by the associated rise in junction temperature ( the die. At approximately 150°C, which is the glass J transition temperature, the plastic changes its properties. Even temporarily exceeding this temperature limit may change the stresses that the package exerts on the die, permanently shifting the parametric performance of the ADA4412-3 ...

... The group delay variation from 1 MHz to 36 MHz in the 36 MHz section is 7 ns, which produces a fast settling pulse response. The ADA4412-3 is designed to operate in many video environ- ments. The supply range single supply or dual supply, and requires a relatively low nominal quiescent current per channel. In single-supply applications, the PSRR is greater than 60 dB, providing excellent rejection in systems with supplies that are noisy or under-regulated ...

... For example, setting LEVEL1 to 300 mV and LEVEL2 shifts the offset voltages at the ADA4412-3 outputs to 600 mV. This particular setting can be used in most single-supply applications to keep the output swings safely above the negative supply rail ...

... VIDEO ENCODER RECONSTRUCTION FILTER The ADA4412-3 is easily applied as a reconstruction filter at the DAC outputs of a video encoder. Figure 20 illustrates how to use the ADA4412-3 in this type of application with an ADV7322 video encoder in a single-supply application with ac-coupled outputs. Rev Page ADA4412-3 75Ω ...
