LT1006

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: 50µV Max Specifications at ±15V are also provided.

Guaranteed Low Drift: 1.3µV/°C Max

The LT1006 has a low offset voltage of 20µV, drift of

Guaranteed Offset Current: 0.5n A Max

0.2µV/°C, offset current of 120p A, gain of 2.5 million,

rejection of 126d B.

17m A Load Current: 0.8 Million Min

Guaranteed Low Supply Current: 520µA Max Although supply current is only 340µA, a novel output Supply Current can be Reduced by a Factor of 4 stage can source or sink in excess of 20m A while retaining Low Voltage Noise, 0.1Hz to 10Hz: 0.55µVP-P high voltage gain. Common mode input range includes Low Current Noise— ground to accommodate low ground-referenced inputs Better than OP-07: 0.07p A/√Hz at 10Hz from strain gauges or thermocouples, and output can High Input Impedance: 250MΩ Min swing to within a few millivolts of ground. If a higher Minimum Supply Voltage: 2.7V Min slew rate (in excess of 1V/µs) or micropower operation (supply current down to 90µA) is required, the operating APPLICATIO S UN IT currents can be modified by connecting an external optional resistor to Pin 8.
