PRODUCT DESCRIPTION
The 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. This
breakthrough product also features high output current drive
capability and the ability to drive an unlimited capacitive load
while still maintaining excellent signal integrity.
The 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).
The AD817 is fully specified for operation with a single +5 V
power supply and with dual supplies from ±5 V to ±15 V. This
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.
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.
The AD817 is available in 8-pin plastic mini-DIP and SOIC
packages.
