General Description
The National CLC5622 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 comple-
mentary 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 CLC5622 offers 0.1dB gain flatness to 30MHz and differen-
tial gain and phase errors of 0.05% and 0.03°. These features are
ideal for professional and consumer video applications.
The CLC5622 offers superior dynamic performance with a
160MHz small-signal bandwidth, 370V/
µs slew rate and 4.4ns
rise/fall times (2Vstep). The combination of low quiescent power,
high output current drive, and high-speed performance make
the CLC5622 well suited for many battery-powered personal
communication/computing systems.
The ability to drive low-impedance, highly capacitive loads,
makes the CLC5622 ideal for single ended cable applications.
It also drives low impedance loads with minimum distortion.
The CLC5622 will drive a 100
Ω load with only -95/-95dBc
second/third harmonic distortion (Av = +2, Vout = 2Vpp, f = 1MHz).
With a 25
Ω load, and the same conditions, it produces only -72/
-77dBc second/third harmonic distortion.
The CLC5622 can also be used for driving differential-input step-
up transformers for applications such as Asynchronous Digital
Subscriber Lines (ADSL) or High-Bit-Rate Digital Subscriber
Lines (HDSL).
When driving the input of high-resolution A/D converters, the
CLC5622 provides excellent -90/-97dBc second/third harmonic
distortion (Av = +2, Vout = 2Vpp, f = 1MHz, RL = 1kΩ) and fast
settling time.
