Fast and Accurate 80MHz Amplifier Draws Only 2mA
Design Note 286
Glen Brisebois, William Jett, Dahn Tran
Introduction
The 80MHz LTВ®1800 ampliп¬Ѓer provides the high speed
and DC accuracy required by low voltage signal conditioning and data acquisition systems while consuming
a mere 2mA max supply current. The LT1800 operates
with supplies from 2.4V to 12V and its rail-to-rail inputs
and outputs allow the entire supply range to be used.
DC performance is exceptional; the maximum offset
voltage is only 350ОјV and the maximum input bias
current is only 250nA. The ampliп¬Ѓer is also available in
dual and quad versions as the LT1801 and the LT1802,
respectively. All are available in commercial and industrial temperature grades. The LT1800 is available in
SO and SOT-23 packages, the LT1801 dual in an SO-8
package and the LT1802 quad in an SO-14 package.
Single Supply 1A Laser Driver
Figure 1 shows the LT1800 used in a 1A laser driver
application. The LT1800 is well suited to this control
task because its 2.4V operation ensures that it is awake
at power-up and in control before the circuit can cause
signiп¬Ѓcant current to п¬‚ow in the 2.1V threshold laser.
Raising the noninverting input of the LT1800 causes its …

DESIGN FEATURES Accurate and Fast 80MHz Amplifier
Draws only 2mA
by William Jett, Danh Tran and Glen Brisebois
Introduction Performance The 80MHz LT1800 amplifier consumes a mere 2mA max supply
current and still provides both the
speed and DC accuracy required by
low voltage signal conditioning and
data acquisition systems. Usually, one
cannot have both high bandwidth
and low supply-current in an amplifier, but the LT1800 optimizes both
through a 6GHz fT process and by
running the transistors at reduced
quiescent currents. It can operate
from supplies as low as 2.5V, and the entire supply range is available because of the deviceвЂ™s rail-to-rail inputs
and outputs. The DC performance is
exceptional, with a maximum offset
voltage of 350ВµV. This comes from
trimming the input offset voltage, and
canceling the input bias currents,
where the maximum input bias current is 250nA. The device is available
in commercial and industrial temperature grades, in both SOIC and
SOT-23 packages, making for a tiny
and versatile amplifier. Table 1 summarizes the performance …
