The LT1673 are ultralow power
(IS ≤ 2µA) decompensated (AV ≥ 5) op amps with precision specifications. The extremely low supply current is
combined with excellent amplifier specifications: input
offset voltage is 375µV maximum with a typical drift of
only 0.4µV/°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
LT1673 easy to use in harsh environments.
