Connect a DC ammeter to the VCC pin and measure.

Connect a DC ammeter to the VCC pin and measure.

Connect a DC ammeter to the VCC pin. Gradually

lower from VC1 =VCC. VC1 voltage when

consumption current is reduced from ICC1 to

110% of ICC2 is VIL. Gradually raise from VC1 =

0V. VC1 voltage when consumption current

increases from ICC2 to 90% of ICC1 is VIH.

From here on, short the ammeter when using it.

Input a 1.0VP-P, 100kHz sine wave to SG1. If TP1

voltage is V1 and TP2 voltage is V2, find GV by the

following formula: GV = 20LOG (V2/V1) dB

In the above GV measurement, if TP2 voltage at

7MHz is V3, find fc by the following formula.

fc = 20LOG (V3/V2) dB

Input a 1.0VP-P staircase to SG1 and measure

differential gain at TP2. APL = 10 ~ 90%

The same as for DG, but measure differential phase.

Input a 100kHz sine wave to SG1. Measure DR, the

maximum amplitude under THD 1%, at TP2.
