Overview
The EL2386CS is a triple current-feedback operational amplifier featuring a 250MHz -3dB bandwidth at unity gain and a 1200V/µs slew rate. It operates on dual supplies from ±1.5V to ±6V or single supplies from +3V to +12V, consuming 3mA per amplifier. The device includes a disable feature reducing current to 0mA and provides an output drive of 55mA.
Feature Summary
- Triple amplifier topology with integrated disable function
- High-speed performance with 250MHz bandwidth
- Low power consumption with 0mA shutdown state
- Robust output drive capability for video applications
Applications
- HDSL amplifiers
- Video amplifiers
- Cable drivers
- RGB amplifiers
- Multiplexing circuits
Procurement Notes
Verify the specific package variant (EL2386CS) against the required reel size and lead-free status (EL2386CSZ). Confirm that the 16-pin SO package dimensions match the PCB footprint requirements. Ensure supply voltage ranges align with the ±1.5V to ±6V specification before finalizing orders.
Selection Notes
Select this component for high-bandwidth applications requiring low power dissipation. The current-feedback architecture maintains consistent bandwidth across varying gains. Consider the EL2170 family if lower power is prioritized over speed, or the EL2180 series if disable functionality is not required.
Part Context
This part belongs to the Intersil/Renesas EL238x series of high-speed current-feedback amplifiers. It serves as the triple-channel version within a lineup that includes single (EL2186), dual (EL2286), and quad (EL2480) configurations. The series is designed for portable computing and video processing systems.
Replacement Considerations
For non-disable versions, consider the EL2180, EL2280, or EL2480. For lower power needs, the EL2170/EL2176 family offers 70MHz bandwidth. Single and dual channel equivalents are available as EL2186 and EL2286 respectively.
FAQ
How does the disable pin affect the output state?
When the ENABLE pin is pulled above 4.5V, the amplifier enters a high-impedance state and consumes 0mA.
What is the recommended feedback resistor value?
The datasheet specifies RF = 750Ω for optimal performance at gains of +1 and +2.
