CHARACTERISTICS
VCCA =V7 to V6 = 2.7 to 3.6 V; VCCD =V10 to V9 = 2.7 to 3.6 V; VCCO =V20 (or V22) to V19 (or V21) = 2.7 to 3.6 V;
AGND to DGND and OGND shorted together; VCCA to VCCD = 0.15 to +0.15 V; VCCD to VCCO = 0.15 to +0.15 V;
VCCA to VCCO = 0.15 to +0.15 V; Tamb = 0 to 70 °C; typical values measured at VCCA =VCCD =VCCO = 3.0 V and
Tamb =25 °C; single-ended input; unless otherwise specied.
