The high drive capability of 450mA makes this driver ideal for both CAP and DMT designs. It contains two pairs of wideband, high-voltage, current mode feedback amplifiers optimized for low power consumption in DSL systems. • Pb-free available These drivers achieve an MTPR distortion measurement of better than 70dB, while consuming typically 5mA per DSL channel of total supply current. This supply current can be set using a resistor on the IADJ pin. Two other pins (C0 & C1) can also be used to adjust supply current to one of four preset modes (full-IS, 3/4-IS, 1/2-IS, and full power-down). The EL1528 operates on ±5V to ±12V supplies and retains its bandwidth and linearity over the complete supply range. The device is supplied in a thermally-enhanced 20-pin HTSSOP and the small footprint (4x5mm) 24-pin QFN packages. The EL1528 is specified for operation over the full -40°C to +85°C temperature range. • 450mA output drive capability • 44.4VP-P differential output drive into 100 • -75dBc THD @ 500kHz 16VP-P • MTPR of -70dB • Operates down to 2mA per amplifier supply current • Current control pins • Channel separation - 80dB @ 500kHz - 75dB @ 1MHz • Pb-free available (RoHS compliant) Applications • Dual port ADSL line drivers • HDSL line drivers • VDSL line drivers Pinouts EL1528 (20-PIN HTSSOP) TOP VIEW 20 VOUTA 21 NC 22 VS- 23 C0AB 24 C1AB EL1528 (24-PIN QFN) TOP VIEW VINA+ 1 19 VINA- VINB+ 2 18 VINB- GND 3 17 VOUTB THERMAL PAD IADJ 4 16 VOUTC 13 VOUTD 1 NC 12 VIND+ 7 NC 11 14 VIND- VS+ 10 VINC+ 6 C0CD 9 15 VINC- C1CD 8 NC 5 C0AB 1 20 VS- C1AB 2 19 VOUTA VINA+ 3 18 VINA- VINB+ 4 17 VINB- GND 5 IADJ 6 THERMAL PAD 16 VOUTB 15 VOUTC VINC+ 7 14 VINC- VIND+ 8 13 VIND- C1CD 9 12 VOUTD C0CD 10 11 VS+ CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 321-724-7143 | Intersil (and design) is a registered trademark of Intersil Americas Inc.
