ELECTRICAL CHARACTERISTICS (continued)

(VDD = +5V, VSS = 0, VCM = 0, VOUT = VDD/2, RL

≥ 1MΩ connected to VDD/2, SHDN = VDD (MAX4481 only), TA = +25°C, unless

otherwise noted.)

ELECTRICAL CHARACTERISTICS

(VDD = +5V, VSS = 0, VCM = 0, VOUT = VDD/2, RL

≥ 1MΩ connected to VDD/2, SHDN = VDD (MAX4481 only), TA = -40°C to +125°C,

unless otherwise noted.) (Note 2)

Note 1: Guaranteed by design.

Note 2: Specifications are 100% tested at TA = +25°C (exceptions noted). All temperature limits are guaranteed by design.
