Analog Output Characteristics (OUTP, OUTN)

Standard voltage: VDD1 = VDD2 = VDD3 = VDD4 = 3.6V, VSS1 = VSS2 = 0V

Note 1. DRCN = HIGH, 217Hz ripple frequency, 0.2Vrms ripple amplitude on VDD1/VDD2/VDD3/VDD4, input and VREF1 connected by 600

Ω.

Low voltage: VDD1 = VDD2 = VDD3 = VDD4 = 2.4V, VSS1 = VSS2 = 0V
