General Description

The CLC450 has a new output stage that delivers high output
drive current (100mA), but consumes minimal quiescent supply
current (1.5mA) 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 CLC450 offers superior dynamic performance with a
100MHz small-signal bandwidth, 280V/µs slew rate and 6.1ns
rise/fall times (2V

step

). The combination of low quiescent power,
high output current drive, and high-speed performance make
the CLC450 well suited for many battery-powered personal
communication/computing systems.

The ability to drive low-impedance, highly capacitive loads,
makes the CLC450 ideal for single ended cable applications. It
also drives low impedance loads with minimum distortion. The
CLC450 will drive a 100Ω load with only -75/-64dBc second/third
harmonic distortion (Av= +2, V

out

= 2Vpp, f = 1MHz). With a 25Ω
load, and the same conditions, it produces only -70/-60dBc 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
CLC450 provides excellent -79/-75dBc second/third harmonic
distortion (Av= +2, V

out

= 2Vpp, f = 1MHz, RL= 1kΩ) and fast

settling time.
Available in SOT23-5, the CLC450 is ideal for applications where

space is critical.
