LT6558

6558f
550MHz, 2200V/µs Gain of 1,
Single Supply Triple Video
Amplifi er with Input Bias Control
The LT
®
6558 is a high speed triple video amplifi er with an
internal fi xed gain of 1 and a programmable DC input bias
voltage. This amplifi er features a 400MHz 2V
P-P
signal
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.

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: A heat sink may be required to keep the junction temperature
below the Absolute Maximum Rating.
Note 3: The LT6558C is guaranteed functional over the temperature range
of –40°C and 85°C.
Note 4: The LT6558C is guaranteed to meet specifi ed performance from
0°C to 70°C. The LT6558C is designed, characterized and expected to
meet specifi ed performance from –40°C to 85°C but is not tested or
QA sampled at these temperatures.The LT6558I is guaranteed to meet
specifi ed performance from –40°C to 85°C.
Note 5: Slew rate is 100% production tested on the R channel and
measured on the rising edge of the output signal. The slew rate of the
falling edge and of the G and B channels is guaranteed through design and
characterization.
Note 6: Large-signal bandwidth is calculated from slew rate:
FPBW = SR/(π • V
