FEATURES
DESCRIPTIO
N

The LT
1495/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 speci-
fications: 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 character-
istics 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 (–18V min) and
inputs that operate above the positive supply make the
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 LT1495 is available in plastic 8-pin PDIP and SO-8
packages with the standard dual op amp pinout. The
LT1496 is available in 14-pin SO and PDIP packages.
