LT6559CUD

Product Summary

The LT6559 is a low cost, high speed, triple amplifi er that has been optimized for excellent video performance on a single 5V supply, yet fi ts in the small footprint of a 3mm ×3mm QFN package. With a –3dB bandwidth of 300MHz, a 0.1dB bandwidth of 150MHz, and a slew rate of 800V/μs,the LT6559’s dynamic performance is an excellent match for high speed RGB or YPBPR video applications.For multiplexing applications such as KVM switches or selectable video inputs, each channel has an independent high speed enable/disable pin. Each amplifi er will turn on
in 30ns and off in 40ns. When enabled, each amplifier draws 3.9mA from a 5V supply. It operates on a single supply voltage ranging from 4V to 12V, and on split supplies ranging from ±2V to ±6V.The LT6559 comes in a compact 16-lead 3mm × 3mm QFN package, and operates over a –40℃ to 85℃ temperature range. It is manufactured on Linear Technology’s proprietary complementary bipolar process.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: This parameter is guaranteed to meet specifi ed performance through design and characterization. It has not been tested.
Note 3: A heat sink may be required depending on the power supply voltage and how many amplifi ers have their outputs short circuited.
Note 4: The LT6559 is guaranteed to meet specifi ed performance from 0℃ to 70℃ and is designed, characterized and expected to meet these extended temperature limits, but is not tested or QA sampled at –40℃ and 85℃.
Note 5: TJ is calculated from the ambient temperature TA and the power dissipation PD according to the following formula: TJ = TA + (PDx68℃/W)
Note 6: The LT6559 is guaranteed functional over the operating temperature range of –40℃ to 85℃.
