ISL1533AIRZ

Overview

The ISL1533AIRZ is a dual-channel differential amplifier designed for DSL line driving applications. It features a high slew rate of 400 V/µs and a 60 MHz bandwidth, supporting output currents up to 450 mA per channel. The device operates on a supply voltage range of 8 V to 30 V with a quiescent current of 4 mA. Key electrical parameters include an input bias current of 50 µA, input offset voltage of 4 mV, and low noise density of 10 nV/√Hz. It is housed in a 24-lead QFN package and functions within a temperature range of -40°C to +85°C.
