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
. The drivers have 120 MHz of
bandwidth and 1,500 V/
μ
s of differential slew rate while
featuring total harmonic distortion of –68 dB at 1 MHz into a
100
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/
μ
s 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).
