CLC5633
Triple, High Output, Programmable Gain Buffer
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/ch) from a single
5V supply. Its current feedback architecture, fabricated in an
advanced complementary bipolar process, maintains consis-
tent 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
differential gain and phase errors of 0.03% and 0.06˚. These
features area 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 (2V_STEP). The combination of low quies-
cent power, high output current drive, and high speed per-
formance 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 (A_V = +2,
V_OUT= 2V_PP, f = 1MHz). With a 25Ω load, and the same
conditions, it produces only −75/−75dBc second/third har-
monic 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 har-
monic distortion (A_V = +2, V_OUT = 2V_PP, f = 1MHz, R_L =
1kΩ) and fast settling time.
