PRODUCT DESCRIPTION
The AD5539 is an ultrahigh frequency operational amplifier de-
signed specifically for use in video circuits and RF amplifiers.
Requiring no external compensation for gains greater than 5, it
may be operated at lower gains with the addition of external
compensation.
As a superior replacement for the Signetics NE/SE5539, each
AD5539 is 100% dc tested to meet all of its guaranteed dc
specifications over the full temperature range of the device.
The high slew rate and wide bandwidth of the AD5539 provide
low cost solutions to many otherwise complex and expensive
high frequency circuit design problems.
The AD5539 is available specified to operate over either the
commercial (AD5539JN/JQ) or military (AD5539SQ) tempera-
ture range. The commercial grade is available either in 14-pin
plastic or cerdip packages. The military version is supplied in
the cerdip package. Chip versions are also available.
