DESCRIPTION
The LT
廬
1495/LT1496 are the lowest power (I
S
鈮?/div>
1.5碌A(chǔ)) op
amps with precision specifications. The extremely low
supply current is combined with excellent amplifier speci-
fications: input offset voltage is 375碌V maximum with a
typical drift of only 0.4碌V/擄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
鹵15V.
Supply rejection is 90dB and the common mode rejection
ratio is 90dB. Operation is specified for 3V, 5V and
鹵15V
supplies. Reverse battery protection (鈥?8V 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碌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.
