The EL1537 is a very low power dual channel differentiatedamplifier designed for central office line driving for DMTADSL solutions. This device features a high drive capabilityof 400mA while consuming only 7.5mA of supply current peramplifier from ±12V supplies. This driver achieves a typicaldistortion of less than -75dBc, at 1MHz into a 50Ω load. TheEL1537 is available in the thermally-enhanced 28-pinHTSSOP package. This device is specified for operationover the full -40°C to +85°C temperature range.The EL1537 has two control pins, C0 and C1, per channel.With the selection of C0 and C1, the device can be set intofull-IS power, 3/4-IS power, 1/2-IS power, and power-downdisable modes. The EL1537 maintains excellent distortionand load driving capabilities even in the lowest powersettings. The EL1537 has extended bandwidth and improvedTHD and slew rate for ADSL2+ and VDSL applications.
