NOTES:

1. All voltage values are with respect to the midpoint between VCC + and VCC – unless otherwise noted.

2. The inputs are protected by back-to-back diodes. Current-limiting resistors are not used in order to achieve low noise. Excessive

input current will flow if a differential input voltage in excess of approximately

± 0.7 V is applied between the inputs unless some

limiting resistance is used.
