DESCRIPTION
The LMH6715 combines TI's VIP10 high speed
complementary bipolar process with TI's current
feedback topology to produce a very high speed dual
op amp. The LMH6715 provides 400MHz small signal
bandwidth at a gain of +2V/V and 1300V/μs slew rate
while consuming only 5.8mA per amplifier from ±5V
supplies.
The LMH6715 offers exceptional video performance
with its 0.02% and 0.02° differential gain and phase
errors for NTSC and PAL video signals while driving
up to four back terminated 75Ω loads. The LMH6715
also offers a flat gain response of 0.1dB to 100MHz
and very low channel-to-channel crosstalk of −70dB
at 10MHz. Additionally, each amplifier can deliver
70mA of output current. This level of performance
makes the LMH6715 an ideal dual op amp for high
density, broadcast quality video systems.
The LMH6715's two very well matched amplifiers
support a number of applications such as differential
line drivers and receivers. In addition, the LMH6715
is well suited for Sallen Key active filters in
applications such as anti-aliasing filters for high
speed A/D converters. Its small 8-pin SOIC package,
low power requirement, low noise and distortion allow
the LMH6715 to serve portable RF applications such
as IQ channels.
