Comlinear CLC453  
Single Supply, Low-Power, High Output,  
Programmable Buffer  
General Description  
Features  
The Comlinear CLC453 is a low cost, high speed (110MHz)  
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 (3.0mA) from a single 5V supply. Its current feedback  
architecture, fabricated in an advanced complementary bipolar  
process, maintains consistent 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 CLC453’s  
internal feedback network provides an excellent gain accuracy  
of 0.3%

The ability to drive low-impedance, highly capacitive loads,  
makes the CLC453 ideal for single ended cable applications. It  
also drives low impedance loads with minimum distortion. The  
CLC453 will drive a 100load with only -72/-74dBc second/third
