EL1537A ® Data Sheet April 19, 2007 Dual Channel Central Office ADSL2+ Line Driver The EL1537A is a very low power dual channel differentiated amplifier designed for central office line driving for DMT ADSL solutions. The EL1537A has a higher output swing specification for driving 30Ω loads as compared to the EL1537. 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 EL1537A is available in the thermally-enhanced 28 Ld HTSSOP package. This device is specified for operation over the full -40°C to +85°C temperature range. FN6134.1 Features • Drives 400mA at 16VP-P on ±12V supplies • 44.4VP-P differential output drive into 100Ω • 40VP-P minimum differential output drive into 60Ω • -75dBc typical driver output distortion driving 50Ω at 1MHz and 1/2-IS bias current • Low quiescent current of 3.9mA per amplifier in 1/2-IS mode • 50MHz BW at AV = 10 • Power-down disable mode • Pin-to-pin replacement for EL1527 The EL1537A 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 EL1537A maintains excellent distortion and load driving capabilities even in the lowest power settings. The EL1537A has extended bandwidth and improved THD and slew rate for ADSL2+ and VDSL applications. • Pb-free plus anneal available (RoHS compliant) Applications • ADSL, ADSL2, ADSL2+ line drivers • G.SHDSL, HDSL2 line drivers • VDSL line drivers • Video distribution amplifiers Ordering Information • Video twisted-pair line drivers PART NUMBER (Note) PART MARKING PACKAGE (Pb-free) TAPE & REEL PKG.
