NOTES: (1) Junction temperature = ambient temperature for low temperature limit and +25

°C Test Level A specifications. Junction temperature = ambient

temperature +23

°C at high temperature limit Test Level A specifications.

(2) Junction temperature = ambient at low temperature limit; junction temperature = ambient +1

°C at high temperature limit for over-temperature

tested specifications.

(3) Test Levels: (A) 100% tested at +25

°C. Over temperature limits by characterization and simulation. (B) Limits set by characterization and

simulation. (C) Typical value for information only.

(4) Current is considered positive out-of-node.

(5) CMIR tested as < 3dB degradation from minimum CMRR at specified limits.

(6) IVH (VH bias current) is positive, and IVL (VL bias current) is negative, under these conditions. See Note 3 and Figures 1 and 12.

(7) Limiter feedthrough is the ratio of the output magnitude to the sinewave added to VH (or VL) when VIN = 0.

(8) VH slew rate conditions are: VIN = +0.7V, G = +6, VL = –2V, VH = step between 2V and 0V. VL slew rate conditions are similar.

(9) Linearity Guardband is defined for an output sinusoid (f = 1MHz, VO = 2VPP) centered between the limiter levels (VH and VL). It is the difference

between the limiter level and the peak output voltage where SFDR decreases by 3dB (see Figure 8).

ELECTRICAL CHARACTERISTICS: VS = ±5V (Cont.)

Boldface limits are tested at +25

°C.

G = +6, RF = 750Ω, RL = 500Ω, VH = –VL = 2V, (Figure 1 for AC performance only), unless otherwise noted.
