ELECTRICAL CHARACTERISTICS (continued)

(VCC = 15V, VEE = -15V, VCM = 0V, RL = 10kΩ to GND, VGND = 0V, TA = -40°C to +125°C. Typical values are at TA = +25°C, unless

otherwise noted.) (Note 3)

Note 3: All devices are 100% production tested at TA = +25°C. Temperature limits are guaranteed by design.
