EL1517ISZ-T7

Overview

The EL1517ISZ-T7 is a single-channel DSL driver manufactured by Elantec, designed for digital subscriber line applications. It operates within a supply voltage range of 4.75 V to 11 V and consumes 14 mA of quiescent current. The device features a gain of 1 V/V, a gain bandwidth product of 200 MHz, and a slew rate of 1100 V/µs. It provides an output current of 60 mA per channel with a common-mode rejection ratio of 65 dB and power supply rejection of 60 dB. Input offset voltage is 1.4 mV, and input bias current is 14 µA. It functions in temperatures from -40°C to +85°C and is housed in an 8-SOIC package.

Feature Summary

• Integrated driver optimized for DSL signal transmission
• High slew rate and wide bandwidth for fast signal response
• Single-channel configuration with 1 V/V fixed gain
