... IOG. Reference Input An external 1.23 V voltage reference is required to drive the ADV7120. The AD589 from Analog Devices is an ideal choice of reference two-terminal, low cost, temperature compensated bandgap voltage reference which provides a fixed 1.23 V output voltage for input currents between 50 A and 5 mA. Figure 4 shows a typical refer- ence circuit connection diagram. The voltage reference gets its current drive from the ADV7120’ ...

... These buffers will also need to be able to supply sufficient cur- 37.5 rent over the complete output voltage swing. Analog Devices produces a range of suitable op amps for such applications. These include the AD84X series of monolithic op amps. In very high frequency applications (80 MHz), the AD9617 is recom- 37 ...
