- Thermal Shutdown Protection
The LT1497 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 ±100mA with only 1.9V of headroom. Twisted pairs can be 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 our complementary bipolar process. The device has characteristics 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.
