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 supplies, the CLC436 consumes only 69mW (Icc= 2.3mA) to provide a 200MHz unity-gain bandwidth, a very fast 2400V/µs slew rate and 13ns rise/fall times (5V step). At ±15V, the device also provides large signal swings (>20Vpp) to give high dynamic 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 videoreconstruction 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.
