The LT
1494/LT1495/LT1496 are the lowest power
(I
S
≤
1.5
μ
A) op amps with precision specifications. The
extremely low supply current is combined with excellent
amplifier specifications: input offset voltage is 375
μ
V
maximum with a typical drift of only 0.4
μ
V/
°
C, input offset
current is 100pA maximum. A minimum open-loop gain
(A
VOL
) of 100V/mV ensures that gain errors are small. The
device characteristics change little over the supply range
of 2.2V to
±
15V. Supply rejection is 90dB and the common
mode rejection ratio is 90dB. Operation is specified for 3V,
5V and
±
15V supplies. Reverse battery protection
(–18Vmin) and inputs that operate above the positive
supply make the LT1494/LT1495/LT1496 easy to use in
harsh environments.
The low bias currents and offset current of the amplifier
permit the use of megohm level source resistors without
introducing significant errors. Voltage noise at 4
μ
V
P-P
is
remarkably low considering the low supply current.
The LT1494 is available in the 8-Pin MSOP, PDIP and SO
packages.The LT1495 is available in plastic 8-Pin PDIP
and SO packages with the standard dual op amp pinout.
The LT1496 is available in 14-Pin SO and PDIP packages.
