The ISL1557IRZ-EVAL evaluation board is used to evaluate the features of the ISL1557 dual operational amplifier which is ideal for ADSL2+, SDSL, HDSL2, and VDSL line driving applications, including both 14.5dBm and 21dBm.
The ISL1557 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.
