Amplifi er with Input Bias Control
550MHz, 2200V/µs Gain of 1,
DESCRIPTION
The LT
internal fi xed gain of 1 and a programmable DC input bias
voltage. This amplifi er features a 400MHz 2V
bandwidth, 2200V/µs slew rate and a unique ability to drive
heavy output loads to 0.8V of the supply rails, making the
LT6558 ideal for a single 5V supply, wideband video applica-
tion. With just one resistor, the inputs of all three amplifi ers
can be programmed to a common voltage level, simplifying
and reducing the need for external circuitry in AC-coupled
applications. Without the programming resistor, the input
bias circuit becomes inactive, allowing the use of an external
clamp circuit or direct coupled input.
The LT6558 has separate power supply and ground pins for
each amplifi er to improve channel separation and to ease
power supply bypassing. The LT6558 provides uncom-
promised performance in many high speed applications
where a low voltage, single supply is required.
The LT6558 is available in 16-lead SSOP and 5mm × 3mm
DFN packages.
