Both the input pin (Pin 1) and the output pin (Pin 9) of the ADCA3992 are matched to 75 Ω. Pin 5 is the VCC pin, 500 which requires 34 V for typical operation, and can support as low as 24 V for lower power operation. It is recommended to mA)450( leave the IADJ pin (Pin 4) open for ful bias operation. For bias NT control on the ADCA3992 supply current, apply an external 400CURRE control voltage between 0 V and 1 V at the IADJ pin. Figure 10 Y L P illustrates the ADCA3992 supply current over control voltages 350UP S at the IADJ pin. 300250 1 1 00.10.20.30.40.50.60.70.80.91.0 0 IADJ (V) 16777- Figure 10.
