FEATURES
DESCRIPTION
U
The LT
1497 dual current feedback amplifier features low
power, high output drive, excellent video characteristics
and outstanding distortion performance. From a low 7mA
maximum supply current per amplifier, the LT1497 drives
±100mAwithonly1.9Vofheadroom.Twistedpairscanbe
driven differentially with – 70dBc distortion up to 1MHz for
±40mA peak signals.
The LT1497 is available in a low thermal resistance 16-pin
SO package for operation with supplies up to
±15V. For
±5V operation the device is also available in a low thermal
resistance SO-8 package. The device has thermal and
current limit circuits that protect against fault conditions.
The LT1497 is manufactured on Linear Technology’s
complementary bipolar process. The device has charac-
teristics that bridge the performance between the LT1229
and LT1207 dual current feedback amplifiers. The LT1229
has 30mA output drive, 100MHz bandwidth and 12mA
supply current. The LT1207 has 250mA output drive,
60MHz bandwidth and 40mA supply current.
