CLC5633
Triple, High Output, Programmable Gain Buffer
June 1999
General Description
The CLC5633 is a triple, low-cost, high-speed (130MHz) buffer
which features user-programmable gains of +2, +1, and -1V/V.
The CLC5633 also has a new output stage that delivers high
output drive current (130mA), but consumes minimal quiescent
supply current (3.0mA/ch) from a single 5V supply. Its current
feedback architecture, fabricated in an advanced complementary
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 CLC5633 offers 0.1dB gain flatness to 20MHz and differen-
tial gain and phase errors of 0.03% and 0.06°. These features are
ideal for professional and consumer video applications.
The CLC5633 offers superior dynamic performance with a
130MHz small-signal bandwidth, 410V/µs slew rate and 5.0ns
rise/fall times (2Vstep). The combination of low quiescent power,
high output current drive, and high-speed performance make
the CLC5633 well suited for many battery-powered personal
communication/computing systems.
The ability to drive low-impedance, highly capacitive loads,
with minimum distortion makes the CLC5633 ideal for cable
applications. The CLC5633 will drive a 100Ω load with only
-73/-92dBc second/third harmonic distortion (Av = +2, Vout =
2Vpp, f = 1MHz). With a 25Ω load, and the same conditions, it
produces only -75/-75dBc second/third harmonic distortion. It is
also optimized for driving high currents into single-ended
transformers and coils.
When driving the input of high-resolution A/D converters, the
CLC5633 provides excellent -92/-96dBc second/third harmonic
distortion (Av = +2, Vout = 2Vpp, f = 1MHz, RL = 1kΩ) and fast
settling time.
