DESCRIPTIO
N
U
The LT
2178 is a micropower dual op amp in a surface
mount standard 8-pin configuration, the LT2179 is a
micropower quad op amp offered in a surface mount 14-pin
package. Both devices are optimized for single supply opera-
tion at 5V. Specifications are also provided at
±
15V supply.
The extremely low supply current is combined with true
precision specifications: offset voltage is 30
μ
V and 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 the megohm
level source resistors without introducing serious errors.
Voltage noise, at 0.9
μ
V
P-P
, is remarkably low considering
the low supply current.
The LT2178/LT2179 can be operated from a single supply
(as low as one lithium-cell or two NiCd batteries). The input
range goes below ground. The all-NPN output stage swings
to within a few millivolts of ground while sinking current. No
power consuming pull down resistors are needed.
For surface mount applications where three times higher
supply current is acceptable, the micropower LT1077
single, LT2078 dual and LT2079 quad are recommended.
The LT1077/LT2078/LT2079 have significantly higher
bandwidth, slew rate, lower voltage noise and better
output drive capability. For applications requiring DIP
packages refer to the LT1178/LT1179.
