EL5455ISZ-T13

Instrumentation, Op Amps, Buffer Amps Overview

The EL5455ISZ-T13 is a quad, 270MHz ultra-accurate voltage mode feedback amplifier manufactured by Renesas Electronics Corporation. It features a maximum offset voltage of ±1mV and an open-loop gain of up to 50kV/V. The device operates on single supplies from 5V to 12V or dual supplies ranging from ±2.5V to ±5V, with a typical supply current of 3mA per amplifier. It provides a slew rate of 180V/µs and an output current capability of 105mA. The component is housed in a 14-lead SOIC package and supports operation across the industrial temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix T13 against official documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status and lead-free material composition requirements prior to procurement. Ensure the selected package variant matches the required board space constraints and thermal dissipation capabilities for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high linearity at elevated frequencies combined with strict DC accuracy. Evaluate the trade-off between feedback resistor values and stability, as larger resistances can reduce phase margin. Consider the output drive capability relative to load resistance to ensure the desired output swing is maintained without exceeding safe operating limits.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the EL5152, EL5153, EL5252, and EL5455 family of wideband, low-power operational amplifiers. While sharing core electrical characteristics such as bandwidth and offset voltage, the EL5455 specifically integrates four independent channels within a single 14-lead SOIC package. This configuration distinguishes it from the single-channel SOT-23 variants and the dual-channel MSOP options within the same product series.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the feedback resistor value affect the stability of the EL5455?

Increasing the feedback resistance shifts a pole into the frequency domain, which reduces the amplifier's phase margin. To maintain stability, it is recommended to keep the feedback resistance between 500Ω and 750Ω or add a small parallel capacitor if higher resistance is necessary.

What is the mechanism for disabling the EL5455 amplifiers?

The EL5455 includes dedicated enable pins (CEA and CEB) for its two pairs of amplifiers. Applying a logic signal above VS+ - 1.5V disables the respective channel, placing the output in a high-impedance state and reducing the supply current to approximately 17µA.
