LT1006 Precision, Single Supply Op Amp UFEATURESDESCRIPTIO ■ 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: 0.5nA Max 0.2µV/°C, offset current of 120pA, gain of 2.5 million, ■ Guaranteed High Gain common mode rejection of 114dB and power supply 5mA Load Current: 1.5 Million Min rejection of 126dB. 17mA Load Current: 0.8 Million Min ■ Guaranteed Low Supply Current: 520 Although supply current is only 340 µA Max µA, a novel output ■ Supply Current can be Reduced by a Factor of 4 stage can source or sink in excess of 20mA while retaining ■ Low Voltage Noise, 0.1Hz to 10Hz: 0.55 high voltage gain. Common mode input range includes µVP-P Low Current Noise— ground to accommodate low ground-referenced inputs Better than OP-07: 0.07pA/ from strain gauges or thermocouples, and output can √Hz at 10Hz ■ High Input Impedance: 250M swing to within a few millivolts of ground. If a higher Ω Min ■ Minimum Supply Voltage: 2.7V Min slew rate (in excess of 1V/µs) or micropower operation (supply current down to 90 U µA) is required, the operating APPLICATIO S currents can be modified by connecting an external optional resistor to Pin 8. ■ Low Power Sample-and-Hold Circuits For similar single supply precision dual and quad op amps, ■ Battery-Powered Precision Instrumentation please see the LT1013/LT1014 data sheet.
