LT1078/LT1079

Micropower, Dual and

Quad, Single Supply, Precision Op Amps

DESCRIPTIO

The LT

1078 is a micropower dual op amp in 8-pin

packages including the small outline surface mount pack-

age. The LT1079 is a micropower quad op amp offered in

the standard 14-pin packages. Both devices are optimized

for single supply operation at 5V.

±15V

specifications are

also provided.

Micropower performance of competing devices is achieved

at the expense of seriously degrading precision, noise,

speed and output drive specifications. The design effort of

the LT1078/LT1079 was concentrated on reducing sup-

ply current without sacrificing other parameters. The

offset voltage achieved is the lowest on any dual or quad

nonchopper stabilized op amp—micropower or other-

wise. Offset current, voltage and current noise, slew rate

and gain bandwidth product are all two to ten times better

than on previous micropower op amps.

The 1/f corner of the voltage noise spectrum is at 0.7Hz,

at least three times lower than on any monolithic op amp.

This results in low frequency (0.1Hz to 10Hz) noise

performance which can only be found on devices with an

order of magnitude higher supply current.

Both the LT1078 and LT1079 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—no power consuming pull

down resistors are needed.
