Amplifier Characteristics  
Figure 1 shows a simplified schematic of one channel of  
the LT6551 quad. Resistors RF and RG provide an internal  
gain of 2. (The LT6550 triple is a slight variation with the  
gain setting resistor, RG, connected to a separate ground  
pin). The input stage consists of transistors Q1 to Q8 and  
resistorR1. Thistopologyallowsforhighslewratesatlow  
supply voltages. There are back-to-back series diodes, D1  
to D4, across the + and – inputs of each amplifier to limit  
the differential input voltage to ±1.4V. RIN limits the  
current through these diodes if the input differential volt-  
age exceeds ±1.4V. The input stage drives the degenera-  
tion resistors of PNP and NPN current mirrors, Q9 to Q12,  
that convert the differential signals into a single-ended  
output. The complementary drive generator supplies cur-  
rent to the output transistors that swing from rail-to-rail.  
the maximum input is (3V – 1.75V) or 1.25V, and the  
internal gain of two will set the output voltage to 2.5V.  
Increasingtheinputbeyond1.25Vwillforcethedeviceout  
of its linear range, no longer a gain of 2, and the output will  
not increase beyond 2.5V. At a higher supply voltage, i.e.  
5V, the maximum input voltage is 5V – 1.75V or 3.25V.  
However, due to the internal gain of 2, the output will clip  
with a lower input voltage. For linear unclipped operation  
the minimum input voltage is (VOUT Min)/2 and the maxi-  
mum input voltage is (VOUT Max)/2 or (VCC – 1.75V),  
whichever is less.  
ESD  
The LT6550/LT6551 have reverse-biased ESD protection  
diodes on all inputs and outputs as shown in Figure 1. If  
these pins are forced beyond either supply, unlimited  
current will flow through these diodes. If the current is  
limited to 10mA or less, no damage to the device will  
occur.  
Input Voltage Range  
The input voltage range is VEE to (VCC – 1.75V) over
