APPLICATIU
FEATURES
DESCRIPTIOU
The LT
1672/LT1673/LT1674 are ultralow power
(I
S
≤
2
μ
A) decompensated (A
V
≥
5) op amps with preci-
sion 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 devices’ 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 (–18V min) and inputs that
operate above the positive supply make the LT1672/
LT1673/LT1674 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. For
unity gain stable versions of these amplifiers, see the
LT1494/LT1495/LT1496.
The LT1672 is available in the 8-pin MSOP, PDIP and SO
packages. The LT1673 is available in plastic 8-pin PDIP
and SO-8 packages with the standard dual op amp pinout.
The LT1674 is available in 14-pin PDIP and SO packages.
