EL5444CSZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL5444CSZ-T7 is a single-channel, voltage-feedback operational amplifier from the EL5144 series, manufactured by Renesas/Intersil. It operates on a single +5V supply and features a unity-gain stable -3dB bandwidth of 100MHz. The device provides rail-to-rail output swing, driving to within 150mV of either rail when loaded with a 75Ω double-terminated coaxial cable. Key electrical parameters include a slew rate of 200V/µs, differential gain of 0.1%, and differential phase of 0.1°. It consumes low power at 35mW per amplifier and offers an input common-mode range from 0V to 3.5V.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation as Renesas or Intersil, as Elantec was acquired. Confirm the package type is SOT-23-5 or similar small outline depending on the specific suffix variant. Check RoHS compliance status and lead time restrictions due to potential end-of-life status. Ensure the part number matches the exact tape-and-reel quantity if T7 indicates reel size.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for single-supply +5V applications requiring high-speed signal processing. It is suitable for composite and component video systems due to low differential gain and phase errors. Consider the rail-to-rail output for maximizing signal swing in low-voltage environments. Verify that the 100MHz bandwidth meets the system's frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL5444 series includes variants like EL5144, EL5244, and EL5344, offering one, two, and four channels respectively. These amplifiers are designed for high-speed, low-power applications. The EL5444CSZ-T7 is a specific channel configuration within this family, optimized for space-saving packages and single-supply operation.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes may include other 100MHz rail-to-rail op-amps from Renesas or competitors. Verify pin compatibility and electrical specifications such as bandwidth and slew rate. Cross-reference with EL5144 variants if channel count differs.
