LTC1490CS8 Dual Micropower Operational Amplifier

The LTC1490CS8 is a high-quality dual operational amplifier (op-amp) designed and manufactured by Linear Technology, which is renowned for its precision electronic components. This op-amp is crafted to meet the needs of applications requiring low power consumption without compromising on performance. The LTC1490CS8 is part of the LTC1490 series and is packaged in a convenient 8-lead SOIC package.

One of the most notable features of the LTC1490CS8 is its micropower operation. It has an incredibly low supply current, which is typically 50µA per amplifier. This feature makes it an ideal choice for battery-powered and portable applications where power efficiency is crucial. Despite its low power usage, the LTC1490CS8 does not sacrifice accuracy or functionality, making it a versatile component for a wide range of electronic designs.

The LTC1490CS8 operates on a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V. This wide range of operating voltages provides design flexibility and allows the op-amp to be used in various circuits without the need for level shifting. Additionally, the input common-mode range includes ground, which is particularly useful for single-supply operations.

The output stage of the LTC1490CS8 is capable of driving heavy loads, providing a minimum output current of 20mA. This makes it suitable for driving not only high impedance loads but also more demanding applications such as actuators or small motors. Moreover, the op-amp features a high open-loop gain, which ensures accurate amplification of input signals.

With a slew rate of 0.45V/µs and a gain-bandwidth product of 200kHz, the LTC1490CS8 is optimized for low-frequency applications such as sensor interfacing, portable instrumentation, and battery-operated systems. It also includes over-temperature protection, enhancing its reliability and longevity in challenging environments.

In summary, the LTC1490CS8 from Linear Technology is a dual micropower operational amplifier that offers a balance between low power consumption and high-performance operation. Its wide voltage supply range, ability to drive heavy loads, and micropower operation make it a versatile choice for designers looking to optimize their power-sensitive applications.
