NOTE:
7. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
Electrical Specifications V+ = 5.0V, V- = GND, RL = Open, RF = 1kΩ, AV = -1 unless otherwise specified. Parameters are per
amplifier. Typical values are at V+= 5V, TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +125°C. (Continued)
