Video Amplifiers

Video amplifiers—can be used in a number

of different ways, but generally they are in the

signal path for amplifying, buffering, filtering or

driving video lines. The specifications of most

interest for composite video signals, or CVBS,

are differential gain and differential phase. For

other video signals, such as YPbPr or RGB,

bandwidth, both small signal and large

signal, and slew rate are of most importance.

Noise and DC accuracy are also considered

important in some high-end applications.

The traditional voltage-feedback (VFB) amplifier

is widely used, because of its ability to be

configured for almost any situation. Many VFB

amplifiers have the ability to accept input

signals going to the negative rail (or ground),

allowing use in many single-supply systems.

Additionally, many VFB amplifiers offer rail-to-

rail outputs offering the widest dynamic range

possible on reduced supplies. Traditional VFB

amplifiers (non-RRO) designed for video offer

the ability to have very high slew rates, wide

bandwidths, low noise, and very good DC

characteristics. Current-feedback amps are

commonly found in high-end video applications,

because of their combination of high slew

rate and excellent output drive at low

quiescent power.

TI is bringing new technology to the market

with the introduction of the

THS7303, THS7313

and

THS7353

. These new three-channel devices

are the first to offer full I

C programmability of

all functions independently for each channel,

which provides the designer the flexibility to

configure a video system as required or on-the-

fly, without the need for hardware upgrades or

modifications. The devices are designed with

integrated Butterworth filters to provide all the

analog signal conditioning required in video

applications such as set-top boxes, digital

televisions, personal video recorders/DVD

readers and portable USB devices. These

highly integrated devices provide space

savings as a result of the high levels of

integration and advanced package technology.

Portable video—Successfully designing a

high-performance video system into low

voltage portable applications requires careful

attention to many small details. Portable

applications impose very challenging technical

requirements beyond those required in typical

video applications and demand particular

trade-offs in performance, power consumption,

printed circuit board space and cost. A DC-

coupled solution with integrated gain,

low-pass filter, level-shifter and shutdown

solves these challenges while maintaining

good video performance—and eliminates the

need for large, expensive discrete components.

The strong combination of integrated features

and optimized design make TI’s OPA360 and

OPA361 especially well suited for use in the

TV-out function in portable designs. The

lowest cost, highest performance and smallest

total solution is achieved by using DC-coupled

input and output, and fits into an area smaller

than 5mm

. Internal gain resistors eliminate

discrete components and the internal level

shifter prevents clipping of the video sync

signal by raising the signal into the amplifier

output’s linear operating range. A shutdown

feature reduces power consumption to 2.5µA

with TV output disabled.

OPA360 is a fully-integrated solution with

on-chip Gain of 2, an integrated 2-pole filter,

and an input level shift circuit. OPA360 is ideally

suited for use with TI’s TMS320DM270/275/320™

and other industry video processors. The new

OPA361 is designed and tested to work

flawlessly with TI’s new OMAP2420 and

DaVinci™ TMS320DM420™ processors and

facilitates automatic TV detection for simpli-

fied end-user interface. For those interested in

tuning their designs for specific characteristics

with a standard video amp, OPA358 offers

excellent, low-cost video performance in a

small SC70 package.
