The LT1178S8 is a micropower dual op amp in the surface
mount 8-pin package. It is optimized for single supply
operation at 5V. Specifications are also provided at
鹵15V
supplies.
The extremely low supply current is combined with true
precision specifications: offset voltage is 60碌V, offset
current is 50pA. Both offset parameters have low drift with
temperature. The 1.5pA
P-P
current noise and picoampere
offset current permit the use of megohm level source
resistors without introducing serious errors. Voltage noise
at 0.9碌V
P-P
is remarkably low considering the low supply
current.
The LT1178S8 can be operated from a single supply as low
as one lithium cell or two Ni-Cad batteries. The input range
goes below ground. The all-NPN output stage swings to
within a few millivolts of ground while sinking current 鈥撯€?/div>
no power consuming pull-down resistors are needed.
For applications where three times higher supply current
is acceptable, the micropower LT1077 single, LT1078
dual and LT1079 quad are recommended. The LT1077/
LT1078/LT1079 have significantly higher bandwidth, slew
rate; lower voltage noise and better output drive capability.
