LMH6732 SNOSA47B – FEBRUARY 2003 – REVISED MARCH 2013 www.ti.com The relationship between ICC and IP is given by: lP = ICC/57 (approximate ratio at ICC = 3.4mA; consult Figure 45 for relationship at any ICC). Knowing IP leads to a direct calculation of RP. RP + 5kΩ = [(V+ -1.6)-V−]/ IP RP+ 5kΩ= =8.4 /IP (for V+ = 5V and V− = −5V). First, an operating point needs to be determined from the plots & specifications as discussed above. From this, IP is obtained.

Controlling Power On State with TTL Logic (Open Collector Output) When the logic gate goes low, the LMH6732 is turned on. The LMH6732 V+ connection would be to +5V supply. Performance desired is that given for ICC = 3.4mA under standard conditions. From the ICC vs. IP plot, IP = 61μA. Then calculating RP: RP + 5kΩ = [(5V-1.

MUX “VOUT” and “Control” Waveform DIFFERENTIAL GAIN AND PHASE Differential gain and phase are measurements useful primarily in composite video channels. They are measured by monitoring the gain and phase changes of a high frequency carrier (3.58MHz for NTSC and 4.
PAGE 21
LMH6732 www.ti.com SNOSA47B – FEBRUARY 2003 – REVISED MARCH 2013 For ICC > 9mA at any closed loop gain setting, a good starting point for RF would be the 9mA value stated in Table 2 above. This value could then be readjusted, if necessary, to achieve the desired response. PRINTED CIRCUIT LAYOUT & EVALUATION BOARDS Generally, a good high frequency layout will keep power supply and ground traces away from the inverting input and output pins.
