EL2045CSZ

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.

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.

Applications

• Video amplifiers
• Active filters and integrators
• High-speed sample-and-hold circuits
• ADC/DAC buffers
• Pulse and RF amplifiers

Procurement Notes

Verify that the specific part number matches the required RoHS-compliant Pb-free designation (EL2045CSZ). Confirm the package type corresponds to the 8-pin SO configuration. Ensure compatibility with the intended supply voltage range and load requirements before finalizing procurement orders.

Selection Notes

Select this component when high speed and low power consumption are critical constraints. The gain-of-2 stability makes it suitable for applications where fixed gain is acceptable. Consider the wide supply range if the design requires flexibility between single and dual supply architectures.

Part Context
