EL2045CN

Overview

The EL2045CN is a high-speed, low-power monolithic operational amplifier manufactured by Elantec Semiconductor. It features a gain-bandwidth product of 100 MHz and a slew rate of 275 V/µs. The device operates on a wide supply voltage range from 2.5V to 36V. It draws a typical supply current of 5.2 mA per amplifier at ±15V. The unit is gain-of-2 stable with a settling time of 80 ns to 0.1% for a 10V step. It offers a differential gain of 0.02% and differential phase of 0.07° at AV = +2.

Feature Summary

• High-speed performance with 100 MHz gain-bandwidth product
• Low power consumption requiring only 5.2 mA supply current per amplifier
• Gain-of-2 stability ensuring reliable operation in non-inverting configurations
• Wide single or dual supply voltage compatibility

Applications

• Video amplifiers
• Active filters and integrators
• ADC/DAC buffers
• High-speed signal processing circuits

Procurement Notes

Verify the manufacturer origin as Elantec Semiconductor, noting that Intersil Corporation acquired Elantec's assets. Confirm the package type matches the CN designation. Check for obsolescence notices or lifecycle status updates from Renesas, the current owner of Intersil products. Ensure the datasheet version corresponds to the specific manufacturing batch requirements.

Selection Notes

Select this component for applications requiring moderate bandwidth and low power dissipation. It is suitable for single-supply designs due to its wide input voltage range. Consider the gain-of-2 stability constraint when designing feedback networks. Compare against the EL2245CN if a dual-channel configuration is required instead of the single-channel EL2045CN.

Part Context

The EL2045CN belongs to the Elantec family of complementary bipolar process operational amplifiers. It serves as the single-channel counterpart to the dual EL2245CN and quad EL2445CN variants. These devices share identical electrical characteristics but differ in channel count and package pinout configurations.
