CLC5602
Dual, High Output, Video Amplifier
General Description
Features
■
The National CLC5602 has a new output stage that delivers high
output drive current (130mA), but consumes minimal
quiescent supply current (1.5mA/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.

Differential A/D driver
The ability to drive low-impedance, highly capacitive loads,
makes the CLC5602 ideal for single ended cable applications.
It also drives low impedance loads with minimum distortion.

Subscriber Lines (ADSL) or High-Bit-Rate Digital Subscriber
Lines (HDSL).
