Product Description:

The EL2044 Terminal is uniquely designed for performing high-precision signal amplification and processing operations with a stable interface with enhanced electrical characteristics. It has an operating voltage supply range of ±5V to ±15V and is therefore suitable for application in a range of applications requiring dual supply systems. EL2044 has a normal input offset voltage of only 3 mV, and this provides extremely little deviation in the input-output accuracy, hence is well-suited for high-precision applications.

The EL2044's input bias current is 0.1 nA, where low-current signal environments and minimizing input loading effects are present. It's gain bandwidth product is 5 MHz, allowing it to process wideband signals without degradation of fidelity. It boasts a slew rate of 1.6 V/µs, which offers clean switching for high-speed signal conditions. The module is powered using an 80 dB common mode rejection ratio (CMRR) which offers enhanced rejection of unwanted noise and interference from differential signals. Furthermore, it gives a power rejection ratio of 90 dB. It ensures stable operations regardless of supply voltage oscillation. Working over a ±12V supply, this terminal offers a full output voltage swing. It proves exceptional signal drive and compatibility with analog components. All amplifiers of the terminal use only a quiescent current of 2.8 mA, minimizing power consumption without any compromise on performance. These features make EL2044 the best for use in sensor signal conditioning, analog filtering, and low-noise stable gain control systems.

The terminal is used in applications concerning electrical accuracy. It is well suited for electrical accuracy applications because of its high noise rejection feature, high-fidelity signal quality, and low offset. It is a good application for analog signal processing within automation and instrumentation systems.
