CLC451
Single Supply, Low-Power, High Output,
Programmable Buffer
General Description
The CLC451 is a low cost, high speed (85MHz) buffer that
features user-programmable gains of +2, +1, and -1V/V. It has a
new output stage that delivers high output drive current (100mA),
but consumes minimal quiescent supply current (1.5mA) from a
single 5V supply. Its current feedback architecture, fabricated in
an advanced complementary bipolar process, maintains consis-
tent performance over a programmable range of gains and wide
signal levels, and has a linear-phase response up to one half of
the -3dB frequency. The CLC451’s internal feedback network
provides an excellent gain accuracy of 0.3%
The CLC451 offers superior dynamic performance with a 85MHz
small-signal bandwidth, 260V/ s slew rate and 6.5ns rise/fall
times (2V
low quiescent power, high output current drive, and high-speed
performance make the CLC451 well suited for many battery-
powered personal communication/computing systems.
The ability to drive low-impedance, highly capacitive loads,
makes the CLC451 ideal for single ended cable applications. It
also drives low impedance loads with minimum distortion. The
CLC451 will drive a 100
harmonic distortion (A
load, and the same conditions, it produces only -55/-60dBc sec-
ond/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
CLC451 provides excellent -66/-75dBc second/third harmonic
distortion (A
