LT1678/LT1679

Dual/Quad Low Noise,

Rail-to-Rail, Precision Op Amps

FEATURES

DESCRIPTIO

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

precisionaswellaslownoisetosinglesupplyapplicationsas

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.

3.9nV/√Hz Typ at 1kHz

5.5nV/√Hz Max at 1kHz

■

Single Supply Operation from 2.7V to 36V

■

Offset Voltage: 100µV Max

■

Low Input Bias Current: 20nA Max

■

High A_VOL: 3V/µV Min, R_L= 10k

■

High CMRR: 100dB Min

High PSRR: 106dB Min

Matching Specifications

No Phase Inversion

8-Lead SO and 14-Lead SO Packages

■

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.
