Precision, Single Supply
Op Amp
FEATURES DESCRIPTIO
Single Supply Operation The LT 1006 is the first precision single supply operational
Input Voltage Range Extends to Ground amplifier. Its design has been optimized for single supply
Output Swings to Ground while Sinking Current operation with a full set of specifications at 5V.
Guaranteed Offset Voltage: 50V Max Specifications at 15V are also provided.
Guaranteed Low Drift: 1.3V/C Max
The LT1006 has a low offset voltage of 20V, drift of
Guaranteed Offset Current: 0.5nA Max
0.2V/C, offset current of 120pA, gain of 2.5 million,
