CHARACTERISTICS
VCCA = V22 to V23 = 4.5 to 5.5 V; VCCD = V6 to V8 = 4.5 to 5.5 V; VCCO = V7 to V8 = 4.2 to 5.5 V; AGND and DGND
shorted together; VCCA to VCCD = 0.5 to +0.5 V; VCCO to VCCD = 0.5 to +0.5 V; VCCA to VCCO = 0.5 to +0.5 V;
Tamb = 0 to +70 °C; typical readings taken at VCCA = VCCD = VCCO = 5 V and Tamb = 25 °C; unless otherwise specied.
