Low Cost 5V/ 5V ꢀ330MH

Triple Video Ampliﬁer

in ꢀmm ꢀmm QFN

DESCRIPTION

FEATURES

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

(A = 1, 2 and –1)

■

0.1dB Gain Flatness: 150MHz (A = 1, 2 and –1)

■

High Slew Rate: 800V/µs

■

80mA Output Current

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.
