T he AD817 is fully specified for operation with a single +5 V
power supply and with dual supplies from ±5 V to ±15 V. T his
power supply flexibility, coupled with a very low supply current
of 7.5 mA and excellent ac characteristics under all power sup-
ply conditions, make the AD817 the ideal choice for many de-
manding yet power sensitive applications.
Available in 8-Pin SOIC and 8-Pin Plastic Mini-DIP

In applications such as ADC buffers and line drivers the AD817
simplifies the design task with its unique combination of a
50 mA minimum output current and the ability to drive
unlimited capacitive loads.
T he AD817 is a low cost, low power, single/dual supply, high
speed op amp which is ideally suited for a broad spectrum of
signal conditioning and data acquisition applications. T his
breakthrough product also features high output current drive
capability and the ability to drive an unlimited capacitive load
while still maintaining excellent signal integrity.
T he AD817 is available in 8-pin plastic mini-DIP and SOIC
packages.
T he 50 MHz unity gain bandwidth, 350 V/µs slew rate and set-
tling time of 45 ns (0.1%) make possible the processing of high
speed signals common to video and imaging systems. Further-
more, professional video performance is attained by offering dif-
ferential gain & phase errors of 0.04% & 0.08° @ 3.58 MHz
and 0.1 dB flatness to 70 MHz (gain = +1).
