Manufacturer:TI Description:The clamped output voltage will not be exactly equal to the voltage applied to VH or VL. Offset errors, mostly due to VBE mismatches, necessitate a clamp accuracy parameter which is found in the device specifications. Clamp accuracy is a function of the clamping conditions. Referring again to Figure 1, it can be seen that one component of clamp accuracy is the VBE mismatch between the QX6 transistors, and the QX5 transistors. If the transistors always ran at the same current level there would be no VBE mismatch, and no contribution to the inaccuracy. The QX6 transistors are biased at a constant current, but as described earlier, the current through QX5 is equivalent to ICLAMP. VBE increases as ICLAMP increases, causing the clamped output voltage to increase as well. ICLAMP is a function of the overdrive level (V-IN -VOUTCLAMPED) and RF, so clamp accuracy degrades as the overdrive increases, or as RF decreases. As an example, the specified accuracy of 60mV for a 2X overdrive with RF = 510Ω degrades to 220mV for RF = 240Ω at the same overdrive, or to 250mV for a 3X overdrive with RF = 510Ω. |
