General Description
The CLC5612 is a dual, low-cost, high-speed (90MHz) buffer
which features user-programmable gains of +2, +1, and
-1V/V. The CLC5612 also has a new output stage that delivers
high output drive current (130mA), but consumes minimal
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 CLC5612 offers 0.1dB gain flatness to 18MHz and differen-
tial gain and phase errors of 0.15% and 0.02°. These features are
ideal for professional and consumer video applications.
The CLC5612 offers superior dynamic performance with a
90MHz small-signal bandwidth, 290V/
μ
s slew rate and 6.2ns
rise/fall times (2V
step
). The combination of low quiescent power,
high output current drive, and high-speed performance make
the CLC5612 well suited for many battery-powered personal
communication/computing systems.
The ability to drive low-impedance, highly capacitive loads,
makes the CLC5612 ideal for single ended cable applications.
It also drives low impedance loads with minimum distortion.
The CLC5612 will drive a 100
load with only -74/-86dBc
second/third harmonic distortion (A
v
= +2, V
out
= 2V
pp
, f = 1MHz).
With a 25
load, and the same conditions, it produces only -70/
-67dBc second/third harmonic distortion. It is also optimized for
driving high currents into single-ended transformers and coils.
When driving the input of high-resolution A/D converters, the
CLC5612 provides excellent -87/-93dBc second/third harmonic
distortion (A
v
= +2, V
out
= 2V

, f = 1MHz, R

) and fast
