NOTES:
2. The input voltage range is defined as: VI+ = – 5.05 V to 5.05 V, VI– = – 5.05 V to 5.05 V, and | VI+ – VI– | ≤ 5.05 V when ANLG
VCC – = – 5 V. The input voltage range is defined as: VI+ = – 0.05 V to 5.05 V, VI– = – 0.05 V to 5.05 V, and | VI+ – VI– | ≤ 5.05 V when
ANLG VCC – = ANLG GND.
3. IO = 4 mA for READY OUT, INT, and D12.
