Renesas ISL1557IRZ-T7

线路接口单元（LIU）±2.25V ~ 6V，4.5V ~ 12V

Overview

The ISL1557IRZ-T7 is a dual operational amplifier designed for VDSL2 and ADSL line driving in DMT based solutions. This device features a high drive capability of 750mA while consuming only 6mA of supply current per amplifier and operating from a single 4.5V to 12V supply. The driver achieves a typical distortion of -80dBc at 150kHz into a 25Ω load.

The ISL1557IRZ-T7 is ideal for ADSL2+, SDSL, HDSL2, and VDSL line driving applications, including both 14.5dBm and 21dBm applications.
