(4) IVH (VH bias current) is positive and IVL (VL bias current) is negative, under these conditions. See Note 2, Figure 47, and Figure 58.
(5) Limiter feedthrough is the ratio of the output magnitude to the sinewave added to VH (or VL) when VIN = 0.
(6) VH slew rate conditions are: VIN = +0.7 V, G = +6, VL = -2 V, VH = step between 2 V and 0 V. VL slew rate conditions are similar.
(7) Linearity Guardband is defined for an output sinusoid (f = 1 MHz, VO = 2 Vp-p) 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 3 dB (see Figure 59).
