CLC5602
Dual, High Output, Video Amplifier
General Description
The National CLC5602 has a new output stage that delivers high
output
quiescent supply current (1.5mA/ch) from a single 5V supply. Its
current feedback architecture, fabricated in an advanced comple-
mentary bipolar process, maintains consistent performance over
a wide range of gains and signal levels, and has a linear-phase
response up to one half of the -3dB frequency.
The CLC5602 offers 0.1dB gain flatness to 22MHz and differen-
tial gain and phase errors of 0.06% and 0.02°. These features are
ideal for professional and consumer video applications.
The CLC5602 offers superior dynamic performance with a
135MHz small-signal bandwidth, 300V/ s slew rate and 5.7ns
rise/fall times (2V
high output current drive, and high-speed performance make
the CLC5602 well suited for many battery-powered personal
communication/computing systems.
The ability to drive low-impedance, highly capacitive loads,
makes the CLC5602 ideal for single ended cable applications.
It also drives low impedance loads with minimum distortion.
The CLC5602 will drive a 100
second/third harmonic distortion (A
With a 25
-72dBc second/third harmonic distortion.
The CLC5602 can also be used for driving differential-input step-
up transformers for applications such as Asynchronous Digital
Subscriber Lines (ADSL) or High-Bit-Rate Digital Subscriber
Lines (HDSL).
When driving the input of high-resolution A/D converters, the
CLC5602 provides excellent -87/-95dBc second/third harmonic
distortion (A
