Junction Temperature = Ambient Temperature + 23 °C at high temperature limit guaranteed specifications. (2) 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. (3) Current is considered positive out of node. (4) CMIR tested as < 3dB degradation from minimum CMRR at specified limits. (5) IVH (VH bias current) is positive, and IVL (VL bias current) is negative, under these conditions. See Note 3 and Figures 1 and 7. (6) Limiter feedthrough is the ratio of the output magnitude to the sinewave added to VH (or VL) when VIN = 0. (7) VH slew rate conditions are: VIN = +0.7V, G = +6, VL = –2V, VH = step between 2V and 0V. VL slew rate conditions are similar. (8) 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).
