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/

µs slew rate and 4.5ns

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

Ω load with only -75/-74dBc second/third

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

settling time.

Available in SOT23-5, the CLC452 is ideal for applications where

space is critical.
