Fast Op Amps Operate Rail-to-Rail on 2.7V
Design Note 241
Glen Brisebois
The new LTВ®1806 and LT1809 are fast operational
ampliп¬Ѓers with rail-to-rail inputs and outputs. The
LT1806 is optimized for low noise (3.5nV/в€љHz) and
offset (100ОјV typical, 550ОјV max) and has a 325MHz
gain bandwidth product. The LT1809 is optimized for
low distortion (вЂ“90dBc to 5MHz) and has a 180MHz
gain bandwidth product. Both ampliп¬Ѓers have 85mA
output drive capability and are fully speciп¬Ѓed over
commercial and industrial temperature ranges on 3V,
5V and В±5V supplies.
Parallel Composite Ampliп¬Ѓer Achieves
Low Distortion into Heavy Loads
Achieving low distortion is difп¬Ѓcult enough and driving
heavy loads only makes the undertaking more difп¬Ѓcult.
Figure 1 shows a parallel composite topology where
each ampliп¬Ѓer is given a different responsibility. Ampliп¬Ѓer U1 is conп¬Ѓgured in a standard gain of 2 to account
for the eventual attenuation caused by the 50О© output
divider. Ampliп¬Ѓer U1 alone can drive the load, but its
distortion п¬Ѓgures would suffer. Therefore, ampliп¬Ѓer
U2 is added in a slightly higher gain and its output is …

for 3V, 5V and В±5V operation and are
available in 8-lead SO and 6-lead

amplifier and reduces the supply current to less than 1mA. Performance
Table 1 summarizes the performance
of the LT1806 and LT1809. Note that
input offset voltage is specified at
both the positive and negative supply
