6.2 Current Measurements

Figure 6-2 Test Set-up for Button Mode Current Measurement

V_MIC must rise above 2.35V (typ) to enter tone mode before measurement is taken.
$I_{M I C - T} = I_{M I C B I A S} - (\frac{V_{M I C} - 1.45}{1.0 k})$	$I_{V S H U N T - T} = (\frac{V_{M I C} - 1.45}{1.0 k}) - I_{V S 2}$

Figure 6-3 Tone Mode Quiescent Current Consumption Measurement

V_MIC must rise above 2.35V (typ) to enter tone mode before V_S2 is applied.	Current measurements are taken during calibration tone.
$I_{M I C - T} = I_{M I C B I A S} - (\frac{V_{M I C} - 1.45}{1.0 k})$	$I_{V S H U N T - T} = (\frac{V_{M I C} - 1.45}{1.0 k}) - I_{V S 2}$
