The LT

®1672/LT1673/LT1674 are ultralow power

(IS ≤ 2µA) decompensated (AV ≥ 5) op amps with preci-

sion specifications. The extremely low supply current is

combined with excellent amplifier specifications: input

offset voltage is 375

µV maximum with a typical drift of

only 0.4

µV/°C, input offset current is 100pA maximum. A

minimum open-loop gain (AVOL) of 100V/mV ensures that

gain errors are small. The devices’ characteristics change

little over the supply range of 2.2V to

±15V. Supply

rejection is 90dB and the common mode rejection ratio is

90dB. Operation is specified for 3V, 5V and

±15V supplies.

Reverse battery protection (–18V min) and inputs that

operate above the positive supply make the LT1672/

LT1673/LT1674 easy to use in harsh environments.

The low bias currents and offset current of the amplifier

permit the use of megohm level source resistors without

introducing significant errors. Voltage noise at 4

µVP-P is

remarkably low considering the low supply current. For

unity gain stable versions of these amplifiers, see the

LT1494/LT1495/LT1496.

The LT1672 is available in the 8-pin MSOP, PDIP and SO

packages. The LT1673 is available in plastic 8-pin PDIP

and SO-8 packages with the standard dual op amp pinout.

The LT1674 is available in 14-pin PDIP and SO packages.
