DESCRIPTION

The LMH6715 combines Texas Instrument's VIP10™

high speed complementary bipolar process with

Texas Instrument'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 low power requirement, low

noise and distortion allow the LMH6715 to serve

portable RF applications such as IQ channels.
