Comlinear CLC436
200MHz, ±15V, Low-Power Voltage Feedback Op Amp
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 (I_cc = 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 (>20V_pp) 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 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.
