DESCRIPTIO

TYPICAL APPLICATIO

Dual/Quad Low Noise,

Rail-to-Rail, Precision Op Amps

■ 8-Lead SO and 14-Lead SO Packages

The LT

®1678/LT1679 are dual/quad rail-to-rail op amps

offering both low noise and precision: 3.9nV/√Hz wideband

noise, 1/f corner frequency of 4Hz and 90nV peak-to-peak

0.1Hz to 10Hz noise are combined with outstanding

precision: 100µV maximum offset voltage, greater than

100dB common mode and power supply rejection and

20MHz gain bandwidth product. The LT1678/LT1679 bring

precision as well as low noise to single supply applications as

low as 3V. The input range exceeds the power supply by

100mV with no phase inversion while the output can swing

to within 170mV of either rail.

The LT1678/LT1679 are offered in the SO-8 and SO-14

packages. A full set of matching specifications are also

provided, facilitating their use in matching dependent appli-

cations such as a two op amp instrumentation amplifier

design. The LT1678/LT1679 are specified for supply volt-

ages of ±15V, single 5V as well as single 3V. For a single

amplifier with similiar performance, see the LT1677 data

sheet.
