General Description

The Comlinear CLC436 is a high-performance, low power,

voltage-feedback operational amplifier that has been designed

for a wide range of low-cost applications. The CLC436 is

specified to operate from dual ±5V to dual ±15V power supplies.

Operating from ±5V supplies, the unity gain stable CLC436

consumes a mere 23mW of power and features a 150MHz

bandwidth and 850V/

µs slew rate. Operating from ±15V power

provide a 200MHz unity-gain bandwidth, a very fast 2400V/

µs

slew rate and 13ns rise/fall times (5V step). At ±15V, the device

range and signal-to-noise ratio.

As a low-power NTSC or PAL video line-driver, the CLC436

delivers low differential gain and phase errors (0.2%, 1.2°) and

very high output drive current of 80mA. When used as a video

ADC driver, the CLC436 offers low Total Harmonic Distortion

(THD) and high Spurious Free Dynamic Range (SFDR).

Because of it’s voltage feedback topology, the CLC436

allows use of reactive elements in the feedback path and can

be

configured

as

an

excellent

active

filter

for

video-

reconstruction DACs.

The CLC436’s combination of low cost and high performance in

addition to its low-power voltage-feedback topology make it a

versatile signal conditioning building block for a wide range

of price-sensitive applications.
