Thermal Overload Protection

The AD816 consists of two high current drive and two low noise amplifiers. These can be configured differentially for driving low impedance loads and receiving signals over twisted pair cable or could be used independently for single ended driving application such as correction circuits within high resolution CRT Monitors.

The two high output drive amplifiers are capable of supplying a minimum of 500 mA continuous output current and up to 1A peak output current, and when configured differentially, 40 V p-p differential output swing can be achieved on ±15 V supplies into a load of 50 W. The drivers have 120 MHz of bandwidth and 1,500 V/ms of differential slew rate while featuring total harmonic distortion of 68 dB at 1 MHz into a 100 W load, specifications required for high frequency telecommunication subscriber line drivers.

The low noise voltage feedback amplifiers are fully independent and can be configured differentially for use as receiver amplifiers within a subscriber line hybrid interface or individually for signal conditioning or filtering. The low noise of 4 nV/Hz and distortion of 68 dB at 1 MHz enable low level signals to be resolved and amplified in the presence of large common-mode voltages. 100 MHz of bandwidth and 180 V/ms of slew rate combined with a load drive capability of 70 mA enable these amplifiers to drive passive filters and low inductance coils. The AD816 has thermal overload protection for system reliability and is available in low thermal resistance power packages. The AD816 operates over the industrial temperature range (40°C to +85°C).
