EL2045CN

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer 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.
