NOTE:
7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
Electrical Specifications V+ = 5V, V- = 0V, VCM = 2.5V, RL = Open, TA = +25°C unless otherwise specified. Boldface limits apply
over the operating temperature range, -40°C to +125°C. (Continued)
