EL5246CY

Overview

The EL5246CY is a dual-channel, single-supply, voltage-feedback operational amplifier from the Intersil EL5144 series. It features a unity gain stable -3dB bandwidth of 100MHz and a slew rate of 200V/µs. The device operates on a +5V supply with rail-to-rail output swing capability. It includes a power-savings disable feature that reduces supply current to 2.6µA within 10ns via the CE pin. The input common-mode range extends from ground to 3.5V. It is housed in an 8-pin MSOP package and supports industrial temperature ranges.

Feature Summary

• Rail-to-rail output swing capability for maximum dynamic range
• Power-down mode reducing supply current to 2.6µA via Chip Enable pin
• High-speed performance with 100MHz bandwidth and 200V/µs slew rate
• Low differential gain and phase error suitable for video applications

Applications

• Video amplifiers
• Multiplexers
• Line drivers
• Sample & hold amplifiers
• Comparators

Procurement Notes

Verify the specific ordering suffix 'CY' corresponds to the 8-pin MSOP package configuration. Confirm RoHS compliance status if lead-free material sets are required for assembly processes. Ensure the supplier documentation matches the Intersil datasheet specifications for the EL5246 family.

Selection Notes

Select this component when high-speed signal processing requires low power consumption during idle states. The dual-channel architecture with independent enable pins makes it suitable for multiplexing applications. Verify that the 5V single-supply operation aligns with the system's power budget and that the MSOP package fits the board space constraints.

Part Context

This part belongs to the EL5144 series of wide bandwidth, single-supply, low-power, rail-to-rail output operational amplifiers. The series includes single, dual, and quad configurations. The EL5246 specifically denotes the dual-channel variant equipped with a power-down feature controlled by the Chip Enable (CE) pin, distinguishing it from the non-disable EL5244 model.

FAQ

How does the Chip Enable (CE) pin function?

Applying a standard TTL low logic level to the CE pin disables the amplifier, reducing supply current to 2.6µA. Allowing the CE pin to float or applying a high logic level enables the amplifier.

What is the input common-mode voltage range?

The input common-mode voltage range extends from the negative rail (GND) to within 1.5V of the positive rail, specified as 0V < VCM < 3.5V at VS = +5V.
