AC ELECTRICAL CHARACTERISTICS—OUTD (continued)

(Typical Application Circuit, VCC = +2.7V to +3.3V, R1 = R2 = R3 = 0

Ω, TA = -40°C to +85°C, unless otherwise noted. Typical values

are at VCC = 3.3V, CSETL = CSETH = VCC, TA = +25°C, unless otherwise noted.) (Note 1)

Note 1: The MAX2016 is tested at TA = +25°C and is guaranteed by design for TA = -40°C to +85°C.

Note 2: Typical minimum and maximum range of the detector at the stated frequency.

Note 3: Dynamic range refers to the range over which the error remains within the ±3dB range.

Note 4: The slope is the variation of the output voltage per change in input power. It is calculated by fitting a root-mean-square

straight line to the data indicated by the RF input power range.

Note 5: The intercept is an extrapolated value that corresponds to the output power for which the output voltage is zero. It is calcu-

lated by fitting a root-mean-square straight line to the data.
