LT1078CN8 Micropower Dual Precision Operational Amplifier DIP-8 (LT1078CN8 IC)
The LT1078CN8 is a high-performance micropower dual precision operational amplifier from Analog Devices. Housed in a standard 8-pin DIP package, it is specifically designed for systems where power consumption must be minimized without sacrificing precision. It features an exceptionally low supply current of only 40uA per amplifier while maintaining a low offset voltage of 70uV.
In India, this IC is a preferred choice for battery-operated handheld instruments, remote sensor signal conditioning, and micropower active filters. It is a dual version of the LT1077 and is pin-compatible with the industry-standard LT1013, offering a significant power-saving upgrade for precision applications.
Key Features
- Ultra-Low Power: Consumes only 40uA max supply current per amplifier, making it ideal for long-life battery applications.
- Single-Supply Operation: Inputs and outputs include ground while operating on a single 5V supply.
- High Precision: Features a very low input offset voltage of 70uV and low offset drift of 0.4uV/C.
- High Output Drive: Capable of driving heavy capacitive loads and providing 5mA of output current.
- No Crossover Distortion: Unique output stage design eliminates the crossover distortion typically found in other micropower op-amps.
- Wide Supply Range: Operates reliably from 2.2V to 36V (single supply) or +/-1.1V to +/-18V (dual supply).
