LT1014DSW Datasheet, PDF (11/26 Pages) Linear Integrated Systems – Single Supply Operation Input Voltage Range Extends to Ground

Applications Information
Low Supply Operation
The minimum supply voltage for proper operation of the
LT1013/LT1014 is 3.4V (three Ni-Cad batteries). Typical
supply current at this voltage is 290µA, therefore power
dissipation is only one milliwatt per amplifier.
Noise Testing
For applications information on noise testing and calcula-
tions, please see the LT1007 or LT1008 data sheet.
