DESCRIPTION

· The ISL1557A is a dual operational amplifier designed for VDSL2 and ADSL line driving in DMT based solutions.
· It features a high drive capability of 750mA with a supply current of 6mA per amplifier, operating from a single 4.5V to 12V supply.
· The device achieves a typical distortion of -80dBc at 150kHz into a 25 Ω load and is designed with stronger output clamps for enhanced protection against lightning transients.
· Available in 16 Ld QFN and 10 Ld HMSOP packages, it operates over the full -40°C to +85°C temperature range.
· It includes two control pins (C0 and C1) for bias and enable/disable control, allowing power adjustment to optimize the performance/power ratio for the application.
