EL5146CSZ

Overview

The EL5146CSZ is a single-supply, voltage-feedback operational amplifier featuring rail-to-rail output swing. It operates on a +5V supply with a -3dB bandwidth of 100MHz at unity gain and a typical slew rate of 200V/µs. The device includes a power-down feature controlled by a Chip Enable (CE) pin, reducing supply current to 2.6µA within 10ns. It offers an input common-mode range from ground to 3.5V and can source 90mA while sinking 65mA. Packaged in an 8-pin SOIC, it supports industrial temperatures from -40°C to +85°C.

Feature Summary

• Rail-to-rail output capability for maximum dynamic range
• Integrated power-down mode via CE pin for low standby consumption
• High-speed performance with 100MHz bandwidth and 200V/µs slew rate
• Single-supply operation optimized for 5V systems

Applications

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

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation. Confirm RoHS compliance status as manufacturing processes may evolve. Ensure the supplier provides valid traceability documents. Check for any obsolescence notices or lifecycle changes directly from Renesas Electronics Corporation before finalizing procurement.

Selection Notes

Select this component for high-speed applications requiring rail-to-rail output on a single 5V supply. The integrated disable function makes it suitable for multiplexing designs where power conservation is critical. Ensure feedback networks are designed to maintain stability given the 100MHz bandwidth. Verify that load conditions do not exceed the specified short-circuit current limits to prevent device damage.

Part Context

The EL5146CSZ belongs to the EL5144 series of wide-bandwidth, single-supply amplifiers manufactured by Renesas Electronics Corporation. This family includes single, dual, and quad configurations with varying pin counts. The EL5146 specifically denotes a dual amplifier configuration with a chip enable pin, distinguishing it from the non-disable EL5144 variant.

FAQ

How does the Chip Enable (CE) pin affect the amplifier's operation?

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

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, specifically 0V < V_CM < 3.5V when operating on a +5V supply.
