CA3140E General Description

The CA3140E is a high-performance, monolithic, CMOS operational amplifier (op-amp) renowned for its versatility and wide range of applications. Operating from a single power supply, it offers low input current, high input impedance, and rail-to-rail output swing. With a typical input offset voltage of 4mV and a slew rate of 5V/μs, it delivers stable operation in various circuit configurations.This op-amp is suitable for battery-powered applications due to its low power consumption, typically drawing around 2.5mA of quiescent current. It features high open-loop gain (typically 200V/mV) and high common-mode rejection ratio (typically 90dB), ensuring accurate signal amplification even in noisy environments.Furthermore, the CA3140E incorporates internal frequency compensation, simplifying circuit design and enhancing stability. Its wide operating temperature range (-55°C to 125°C) makes it suitable for harsh environments.With its combination of performance, low power consumption, and wide operating range, the CA3140E remains a popular choice for various precision analog applications, including instrumentation amplifiers, active filters, and sensor signal conditioning circuits
