Description
The EL1527 is a very low power dual channel differentiated 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 EL1527 has two control pins, C0 and C1, per channel. With the selection of C0 and C1, the device can be set into full-IS power, 3/4-IS power, 1/2-IS power, and power-down disable modes. The EL1527 maintains excellent distortion and load driving capabilities even in the lowest power settings.
The EL1527 is available in the thermally-enhanced 28-pin HTSSOP package. This device is specified for operation over the full -40oC to +85oC temperature range.
Applications
- ADSL G.DMT and G.lite CO line driving
- G.SHDSL, HDSL2 line drivers
