EL2045CSZ

Instrumentation, Op Amps, Buffer Amps Overview

The EL2045CSZ is a low-power, gain-of-2 stable operational amplifier manufactured by Renesas Electronics Corporation. It features a 100MHz gain-bandwidth product and a 275V/µs slew rate at a supply current of 5.2mA. The device supports dual supplies from ±2V to ±18V or single supplies from 2.5V to 36V. It provides an output voltage swing of ±13.6V with a ±15V supply and 1kΩ load. The component utilizes a conventional voltage-feedback topology and is housed in an 8-pin SO package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Gain-of-2 stability ensures reliable performance in standard non-inverting configurations without requiring external compensation components.
• Conventional voltage-feedback topology allows the integration of reactive or non-linear elements within the feedback network for complex signal processing.
• Wide power supply operating range accommodates both dual-rail and single-supply systems, facilitating operation on low-voltage rails such as +3V or +5V.
