SNOS956E – JUNE 2001 – REVISED AUGUST 2014

6.6 5V Electrical Characteristics

Unless otherwise specified, all limits ensured for V

+ = +5V, V− = −0V, V

CM = 2.5V, AV = +1, RF = 25 Ω for gain = +1,

RF = 402Ω for gain ≥ +2, and RL = 100Ω to V

+/2. Boldface limits apply at the temperature extremes.

(1)

All limits are specified by testing or statistical analysis.

(2)

Typical Values represent the most likely parametric norm.

(3)

Slew rate is the slower of the rising and falling slew rates. Slew rate is rate of change from 10% to 90% of output voltage step.

(4)

Offset voltage average drift is determined by dividing the change in VOS at temperature extremes into the total temperature change.
