Description
The EL1507 is a very low power dual operational amplifier designed for central office and customer premise line driving for DMT ADSL solutions. This device features a high drive capability of 400mA while consuming only 7.5mA of supply current per amplifier from ±12V supplies. This driver achieves a typical distortion of less than -75dBc, at 1MHz into a 50Ω load. The EL1507 is available in the thermallyenhanced 16 Ld SO package, as well as a 16 Ld QFN package. Both are specified for operation over the full -40°C to +85°C temperature range.
The EL1507 has two control pins, C0 and C1. With the selection of C0 and C1, the device can be set into full-IS power, ¾-IS power, ½-IS power, and power down disable modes. The EL1507 maintains excellent distortion and load driving capabilities even in the lowest power settings.
Applications
- ADSL G.DMT and G.lite CO line driving
- G.SHDSL, HDSL2 line driver
