AD815 High Output Current Differential Driver

The AD815 is available in a 24-pin SOIC (RB) and is rated over the industrial temperature range (-40°C to +85°C). The 24-lead SOIC (RB) is capable of driving 26 dBm for full rate ADSL with proper heat sinking.

The AD815 consists of two high speed amplifiers capable of supplying a minimum of 500 mA. They are typically configured as a differential driver enabling an output signal of 40 V p-p on ±15 V supplies. This can be increased further with the use of a coupling transformer with a greater than 1:1 turns ratio. The low harmonic distortion of −66 dB @ 1 MHz into 200 Ω combined with the wide bandwidth and high current drive make the differential driver ideal for communication applications such as subscriber line interfaces for ADSL, HDSL and VDSL.

The AD815 differential slew rate of 900 V/µs and high load drive are suitable for fast dynamic control of coils or transformers, and the video performance of 0.05% and 0.45° differential gain and phase into a load of 25 Ω enable up to 12 back-terminated loads to be driven.
