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 …

= 2VP-P). Both parts are fully specified
for 3V, 5V and В±5V operation and are
available in 8-lead SO and 6-lead
SOT-23 packages. A shutdown function is included that disables the
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
rails, in contrast to most competitive
parts, which are only specified at midsupply. Table 1. LT1806/LT1809 key performance specifications LT1806 LT1809 Gain-Bandwidth Product 325MHz 180MHz Slew Rate 140V/Вµs 350V/Вµs Input Voltage Noise 3.5nV/в€љHz 16nV/в€љHz Harmonic Distortion, RL = 1k
