LT6559
Low Cost 5V/±5V 300MHz
Triple Video Amplifier
in 3mm × 3mm QFN
DESCRIPTION
The LT^®6559 is a low cost, high speed, triple amplifier that
has been optimized for excellent video performance on a
single 5V supply, yet fits 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 YP_BP_R 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.
