3 / 12 page

(VDD = +15V, VSS = -15V, RL = 10kΩ to VGND = 0V, VIN_+ = VIN_- = VGND = 0V, VSHDN = 0V (MAX44291 only), TA = -40°C to +125°C.

Typical values are at TA = +25°C, unless otherwise noted.) (Note 2)

Note 2: All devices are 100% production tested at TA = +25°C. Temperature limits are guaranteed by design.

Note 3: Guaranteed by design.
