• Analog Voltage Range (VDD – VEE) = 3.0 to 18 V Note: VEE must be _ VSS
• Linearized Transfer Characteristics
• Low–noise – 12 nV//Cycle, f . 1.0 kHz Typical
This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum
rated voltages to this high–impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS _ (Vin or Vout) _ VDD. Unused inputs must always be tied to an appropriate logic
voltage level (e.g., either VSS, VEE or VDD). Unused outputs must be left open.
