Medium Power Differential Line Driver Features General Description • Drives up to 250mA from a +12V supply • 20VP-P differential output drive into 100Ω • -85dBc typical driver output distortion at full output at 150kHz • Low quiescent current of 7.5mA per amplifier The EL1509C is a dual operational amplifier designed for customer premise line driving in DMT ADSL solutions. This device features a high drive capability of 250mA while consuming only 7.1mA of supply current per amplifier and operating from a single 5V to 12V supply. This driver achieves a typical distortion of less than -85dBc, at 150kHz into a 25Ω load. The EL1509C is available in the industry standard 8-pin SO as well as the thermally-enhanced 8-pin LPP package. Both are specified for operation over the full -40°C to +85°C temperature range.
