Medium Power Differential Line Driver Features General Description • Drives up to 360mA from a +15V supply • 16VP-P differential output drive into 25Ω and 20VP-P differential output drive into 100Ω • -85dBc typical driver output distortion at full output at 150kHz • Low quiescent current of 3.5mA per amplifier at ½-IS current mode • Disable down to 1.5mA The EL1511C is a dual operational amplifier designed for customer premise line driving in DMT ADSL solutions. This device features a high drive capability of 360mA while consuming only 7.5mA of supply current per amplifier and operating from a single 5V to 15V supply. This driver achieves a typical distortion of less than -85dBc, at 150kHz into a 25Ω load. The EL1511C is available in the thermallyenhanced 16-pin SO (0.150") and a 16-pin LPP (4x4mm) packages. The EL1511C is specified for operation over the full -40°C to +85°C temperature range. Electrical characteristics are given for typical 12V supply operation. Applications The EL1511C has two control pins, C0 and C1, which allow the selection of full IS power, ¾-IS, ½-IS, and power-down modes. ADSL CSA line driving ADSL full rate CPE line driving G.SHDSL, HDSL2 line driver Video distribution amplifier Video twisted-pair line driver Ordering Information The EL1511C maintains excellent distortion and load driving capabilities even in the lowest power settings. 7” MDP0027 16-Pin SO (0.150”) 13” MDP0027 EL1511CL 16-Pin LPP - MDP0046 EL1511CL-T7 16-Pin LPP 7” MDP0046 EL1511CL-T13 16-Pin LPP 13” MDP0046 NC 1 VOUTA 2 16 VS+ + - + - VIN-A 3 15 VOUTB 14 VIN-B NC 1 GND* 4 13 GND* INA- 2 GND* 5 12 GND* INA+ 3 VIN+A 6 GND 7 Power Control Logic 10 C1 9 C0 12 NC Amp A + Amp B + 11 INB10 INB+ Power Control Logic GND 4 9 C1 EL1511CL (16-Pin LPP Top View) EL1511CS [16-Pin SO (0.150”)] * These GND pins are heat spreaders Note: All information contained in this data sheet has been carefully checked and is believed to be accurate as of the date of publication; however, this data sheet cannot be a “controlled document”.
