General Description

The Comlinear CLC408 delivers high output drive current

(96mA), but consumes minimal quiescent supply current

(1.5mA). Its current feedback architecture, fabricated in an

advanced complementary bipolar process, maintains consistent

performance over a wide range of gains and signal levels.

The CLC408 offers superior dynamic performance with a

130MHz small-signal bandwidth, 350V/

µs slew rate and 4.6ns

high output drive current, and high-speed performance make

the CLC408 a great choice for many portable and battery-

powered personal communication and computing systems.

The CLC408 drives low-impedance loads, including capacitive

loads, with little change in performance. Into a 100

Ω load, it

conditions, it produces only -67/-62dBc second/third harmonic

distortion. It is also an excellent choice for driving high currents

into single-ended transformers and coils.

When driving the input of high resolution A/D converters, the

CLC408 provides excellent -85/-75dBc second/third harmonic
