CLC5612

Dual, High Output, Programmable Gain Buffer

General Description

Features

■

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.

Applications

■

Video line driver

■

Coaxial cable driver

■

Twisted pair driver

The CLC5612 offers superior dynamic performance with a

90MHz small-signal bandwidth, 290V/µs slew rate and 6.2ns

the CLC5612 well suited for many battery-powered personal

communication/computing systems.

Maximum Output Voltage vs. R_L

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 100Ω load with only -74/-86dBc

out

With a 25Ω 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.

V_s= +5V

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

CLC5612 provides excellent -87/-93dBc second/third harmonic
