ISL1533AIRZ-T13

Overview

The ISL1533AIRZ-T13 is a dual-channel differential amplifier designed for DSL line driving applications. It operates within a supply voltage range of 8 V to 30 V and draws a typical operating current of 4 mA. The device features a high slew rate of 400 V/µs and a 3 dB bandwidth of 60 MHz. Each channel provides an output current capability of 450 mA, with an input bias current of 50 µA and an input offset voltage of 4 mV. Noise performance includes an input voltage noise density of 10 nV/√Hz and an input noise current density of 25 pA. It is housed in a QFN-24 package and functions reliably across a temperature range of -40°C to +85°C.

Procurement Notes

Verify component authenticity through official Renesas channels or authorized distributors. Confirm the specific suffix T13 indicates reel packaging. Check RoHS compliance status as indicated in official documentation. Ensure the part meets the required industrial temperature range specifications for the intended deployment environment.

Selection Notes

Select this component when a dual-channel solution with high slew rate and significant output current is required. Compare against single-channel alternatives if only one path is needed. Verify that the 8 V minimum supply voltage aligns with the system power rails. Consider the QFN-24 package constraints for PCB layout and thermal management requirements.
