NOTE:

3. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.

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, temperature data guaranteed by characterization. (Continued)
