LT1014CN Quad Precision Operational Amplifier DIP-14 (LT1014CN IC)
The LT1014CN is a high-performance quad precision operational amplifier that serves as a significant upgrade to industry-standard 14-pin configurations like the LM324. Housed in a 14-pin DIP package, it integrates four precision amplifiers on a single chip, featuring a low offset voltage of 150µV and a low drift of 2µV/°C. This allows for high-accuracy circuit designs in a space-saving quad format without the performance trade-offs typical of older multi-channel op-amps.
In the Indian market, this IC is a staple for industrial instrumentation, thermocouple amplifiers, and 4mA-to-20mA current loop transmitters. Its design allows it to operate from a single 5V supply, where both its input common-mode range and output swing include ground, making it ideal for precision signal conditioning in low-voltage, battery-powered systems.
Key Features
- Precision Quad Architecture: Four amplifiers with specifications matching single precision op-amps in one 14-pin package.
- Single-Supply Efficiency: Fully specified for single 5V operation, with inputs and outputs that extend to ground.
- Low Power Consumption: Each amplifier uses only 350µA, reducing the power footprint for portable devices.
- High Drive Capability: The output stage can source and sink over 20mA, allowing it to drive heavy loads while maintaining gain.
- Drop-in Upgrade: Pin-compatible with LM324, LM348, and OP-11, making it easy to improve legacy designs.
- Superior Noise Specs: Features low voltage noise (0.55µVp-p) and an excellent common-mode rejection of 117dB.
