CLC5632 Dual, High Output, Programmable Gain Buffer
December 2000
CLC5632
Dual, High Output, Programmable Gain Buffer
General Description
The CLC5632 is a dual, low cost, high speed (130MHz)
buffer which features user programmable gains of +2, +1,
and −1V/V. The CLC5632 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 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 CLC5632 offers 0.1dB gain flatness to 30MHz and
differential gain and phase errors of 0.08% and 0.02˚. These
features are ideal for professional and consumer video ap-
plications.
The CLC5632 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 CLC5632 well suited for many battery
powered personal communication/computing systems. The
ability to drive low impedance, highly capacitive loads,
makes the CLC5632 ideal for single ended cable applica-
tions. It also drives low impedance loads with minimum
distortion. The CLC5632 will drive a 100Ω load with only
−82/−69dBc second/third harmonic distortion (A
V
= +2,
V
OUT
= 2V
PP
, f = 1MHz). With a 25Ω load, and the same
conditions, it produces only −71/−73dBc 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 CLC5632 pro-
vides excellent −86/−96dBc second/third harmonic distortion
(A
V
= +2, V
OUT
= 2V
PP
, f = 1MHz, R
L
= 1kΩ) and fast
settling time.
