Overview
The EL2245CS is a dual, high-speed, low-power monolithic operational amplifier manufactured by Intersil. Built on a complementary bipolar process, it features a gain-bandwidth product of 100MHz and a slew rate of 275V/µs at a gain of two. The device operates with a wide supply voltage range from 2.5V to 36V and draws only 5.2mA of supply current per amplifier. It offers fast settling time of 80ns to 0.1% for a 10V step and supports a wide output voltage swing.
Feature Summary
- Gain-of-two stability ensures reliable performance in non-inverting configurations without oscillation risks.
- Low power consumption design minimizes energy usage while maintaining high-speed signal processing capabilities.
- Wide supply voltage range accommodates diverse system requirements from single-supply to dual-rail applications.
Applications
- Video amplifiers
- Active filters and integrators
- ADC/DAC buffers
- High-speed signal processing
Procurement Notes
Verify the specific suffix 'CS' indicates the plastic SOIC package variant when sourcing replacements. Confirm manufacturer lineage as Intersil or Renesas Electronics, following the corporate acquisition history. Ensure datasheet revisions match the required electrical specifications for your circuit design.
Selection Notes
Select this component for applications requiring high bandwidth and low power dissipation simultaneously. The dual configuration reduces board space compared to single-channel alternatives. Verify that the operating temperature range meets environmental constraints and that the supply voltage remains within the specified 2.5V to 36V limits for optimal performance.
Part Context
The EL2245CS belongs to the EL2045 family of operational amplifiers, sharing core architectural benefits such as high slew rate and low noise. It serves as the dual-channel counterpart to the quad EL2445, offering identical electrical characteristics in a smaller footprint suitable for compact electronic designs.
Replacement Considerations
Direct functional equivalents include the EL2445CS for quad-channel integration if pin compatibility allows redesign. Cross-reference with other 100MHz gain-of-two stable op-amps from manufacturers like Analog Devices or Texas Instruments for pin-compatible swaps if necessary.
