General Description
The CLC452 has a new output stage that delivers high output
drive current (100mA), but consumes minimal quiescent supply
current (3.0mA) from a single 5V supply. Its current feedback
architecture, fabricated in an advanced complementary 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 CLC452 offers superior dynamic performance with a
130MHz small-signal bandwidth, 400V/
μ
s slew rate and 4.5ns
rise/fall times (2V
step
). The combination of low quiescent power,
high output current drive, and high-speed performance make
the CLC452 well suited for many battery-powered personal
communication/computing systems.
The ability to drive low-impedance, highly capacitive loads,
makes the CLC452 ideal for single ended cable applications. It
also drives low impedance loads with minimum distortion. The
CLC452 will drive a 100
load with only -75/-74dBc second/third
harmonic distortion (A
v
= +2, V
out
= 2V
pp
, f = 1MHz). With a 25
load, and the same conditions, it produces only -65/-77dBc sec-
ond/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
CLC452 provides excellent -78/-85dBc second/third harmonic
distortion (A
v
= +2, V
out
= 2V
pp
, f = 1MHz, R
L
= 1k
) and fast
settling time.
Available in SOT23-5, the CLC452 is ideal for applications where
space is critical.
