The LT1497 is a dual current feedback amplifier that 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 LT1497 is a dual current‑feedback amplifier that provides high output‑drive capability with low power consumption. It operates from a wide supply range of +2.5 V to +15 V, delivers up to +125 mA output current, and features a 50 MHz small‑signal bandwidth and 900 V/µs slew rate.
Typical applications include twisted‑pair drivers, video amplifiers, cable drivers and test‑equipment amplifiers. The device includes thermal shutdown protection and can drive capacitive loads when the appropriate feedback resistor is selected. Package options are 16‑lead SO and 8‑lead SO‑8 for +5 V operation.
