The LT1006 is the first precision single supply operational amplifier. Its design has been optimized for single supply operation with a full set of specifications at 5V. Specifications at ±15V are also provided.The LT1006 has a low offset voltage of 20µV, drift of 0.2µV/°C, offset current of 120pA, gain of 2.5 million, common mode rejection of 114dB and power supply rejection of 126dB.Although supply current is only 340µA, a novel output stage can source or sink in excess of 20mA while retaining high voltage gain. Common mode input range includes ground to accommodate low ground-referenced inputs from strain gauges or thermocouples, and output can swing to within a few millivolts of ground. If a higher slew rate (in excess of 1V/µs) or micropower operation (supply current down to 90µA) is required, the operating currents can be modified by connecting an external optional resistor to Pin 8.For similar single supply precision dual and quad op amps, please see the LT1013/LT1014 datasheet. For micropower dual and quad op amps, please see the LT1078/LT1079 data sheet.ApplicationsLow Power Sample and Hold CircuitsBattery Powered Precision InstrumentationStrain Gauge Signal ConditionersThermocouple Amplifiers4mA to 20mA Current Loop TransmittersActive Filters

The LT1010 is a fast, unity-gain buffer that can increase the output capability of existing IC op amps by more than an order of magnitude. This easy-to-use part makes fast amplifiers less sensitive to capacitive loading and reduces thermal feedback in precision DC amplifiers.Designed to be incorporated within the feedback loop, the buffer can isolate almost any reactive load. Speed can be improved with a single external resistor. Internal operating currents are essentially unaffected by the supply voltage range. Single supply operation is also practical.This monolithic IC is supplied in 8-pin miniDIP, plastic TO-220 and 8-pin DFN packages. The low thermal resistance power package is an aid in reducing operating junction temperatures.ApplicationsBoost Op Amp OutputIsolate Capacitive LoadsDrive Long CablesAudio AmplifiersVideo AmplifiersPower Small MotorsOperational Power SupplyFET Driver

The LT1012 is an internally compensated universal precision operational amplifier which can be used in practically all precision applications. The LT1012 combines picoampere bias currents (which are maintained over the full –55°C to 125°C temperature range), microvolt offset voltage (and low drift with time and temperature), low voltage and current noise, and low power dissipation. The LT1012 achieves precision operation on two Ni-Cad batteries with 1mW of power dissipation. Extremely high common mode and power supply rejection ratios, practically unmeasurable warm-up drift, and the ability to deliver 5mA load current with a voltage gain of one million round out the LT1012’s superb precision specifications.The all around excellence of the LT1012 eliminates the necessity of the time consuming error analysis procedure of precision system design in many applications; the LT1012 can be stocked as the universal internally compensated precision op amp.ApplicationsReplaces OP-07 While Saving PowerPrecision InstrumentationCharge IntegratorsWide Dynamic Range Logarithmic AmplifiersLight MetersLow Frequency Active FiltersThermocouple Amplifiers
