Typical Application
Description
The LT6559 is a low cost, high speed, triple amplifier 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 amplifier will turn on in 30ns and off in 40ns. When enabled, each amplifier draws 3.9mA from a 5V supply. The LT6559 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°C to 85°C temperature range. The LT6559 is manufactured on Linear Technology’s proprietary complementary bipolar process.
