PRODUCT DESCRIPTION
The AD816 consists of two high current drive and two low
noise amplifiers. These can be configured differentially for driv-
ing 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 telecom-
munication subscriber line drivers.
The low noise voltage feedback amplifiers are fully independent
and can be configured differentially for use as receiver amplifi-
ers 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).

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD816 is limited by the associated rise in junction temperature.
The maximum safe junction temperature for the plastic encap-
sulated parts is determined by the glass transition temperature
of the plastic, about 150°C. Exceeding this limit temporarily
may cause a shift in parametric performance due to a change in
the stresses exerted on the die by the package. Exceeding a
junction temperature of 175°C for an extended period can result
in device failure.
The AD816 has thermal shutdown protection, which guarantees
that the maximum junction temperature of the die remains below a
safe level. However, shorting the output to ground or either power
supply for an indeterminate period will result in device failure.
To ensure proper operation, it is important to observe the derat-
ing curves and refer to the section on power considerations.
It must also be noted that in high (noninverting) gain configura-
tions (with low values of gain resistor), a high level of input
overdrive can result in a large input error current, which may
result in a significant power dissipation in the input stage. This
power must be included when computing the junction tempera-
ture rise due to total internal power.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD816 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
