EL2045CN

Overview

The EL2045CN is a low-power, high-speed operational amplifier manufactured by Renesas Electronics Corporation (formerly Intersil). It features a gain-bandwidth product of 100MHz at a gain of +2 and a slew rate of 275V/µs. The device operates on dual supplies from ±2V to ±18V or single supplies from 2.5V to 36V. It draws 5.2mA of supply current at ±15V and provides an output short-circuit current of up to 75mA. The component is housed in an 8-pin PDIP package.

Feature Summary

• Gain-of-2 stability with conventional voltage-feedback topology
• Wide supply voltage range supporting single-supply operation down to 2.5V
• High output drive capability suitable for low impedance loads
• Low differential gain and phase distortion for video applications

Applications

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

Procurement Notes

Verify the specific manufacturer source, as the EL2045 was originally produced by Intersil before its acquisition by Renesas. Confirm that the 8-pin PDIP package matches your board design requirements. Ensure compatibility with RoHS standards if lead-free compliance is necessary for your assembly process.

Selection Notes

Select this component when a voltage-feedback architecture is required for reactive feedback networks, unlike current-feedback alternatives. It is suitable for designs needing wide bandwidth with moderate power consumption. Consider the 8-pin PDIP package constraints regarding thermal dissipation and PCB space compared to surface-mount options.

Part Context

The EL2045 series belongs to a family of high-speed monolithic operational amplifiers built on complementary bipolar processes. While many variants exist in SOIC packages, the EL2045CN specifically denotes the through-hole PDIP version. This part is designed for cost-sensitive applications requiring high speed and low power consumption.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the EL20xx series. Verify electrical parameters such as slew rate and bandwidth against the original requirements when considering alternative high-speed op-amps.

FAQ

Is the EL2045 stable at a gain of +1?

No, the EL2045 is specified as gain-of-2 stable. It may require external compensation or a higher noise gain for stability at unity gain.

What is the maximum supply voltage for the EL2045CN?

The absolute maximum supply voltage is ±18V for dual supplies or 36V for single-supply operation.
