11. Static characteristics

Table 7: Static characteristics

VCC = 12 V; Tamb = 25 °C; RL = 8 Ω; VMODE = 0 V; Vi = 0 V; measured in test circuit Figure 3; unless otherwise specified.

Symbol	Parameter	Conditions		Min	Typ	Max	Unit

		standby mode		VCC − 0.5	-	VCC	V
IMODE	mode selection input current	0 < VMODE < VCC		-	-	20	μA

[1]With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal to the differential output voltage offset (ΔVOUT) divided by the load resistance (RL).

[2]The DC output voltage with respect to ground is approximately 0.5VCC.

[3]ΔVOUT = VOUT+ − VOUT− .
