GENERAL DESCRIPTION  
The AL1210 is an extremely fast and accurate monolithic  
track and hold amplifier. Even at input frequencies of up to  
20MHz, and sampling rates of 50MSPS, its outstanding  
performance allows full 12-bit linearity to be maintained. Under  
these extremely fast conditions, the TOTAL harmonic  
distortion introduced by the AL1210 is still only -70dBc.  
Its primary application is as a track and hold with the new  
generation high speed flash A/D converters. By using the  
AL1210 with these converters, it is now possible to obtain  
meaningful 10-bit performance at input frequencies of up to  
40MHz and sampling rates of up to 75MSPS. If the AL1210  
were not used, the meaningful resolution would drop down to 6  
bits or less. At 50MHz the TOTAL harmonic distortion is  
only -59dBc.

The noise that a track and hold circuit generates must be  
significantly below the resolution or noise of the A/D converter  
in order not to limit the dynamic range of the system. The causes  
of noise in a track and hold are quite complex and come from  
several sources. In the AL1210 these noise sources are kept very  
low, for example, an aperture jitter of only 1ps and a total output  
noise of only 50µV.

To obtain this remarkable performance, innovative  
circuit design and careful layout have been used. It is fabricated  
in a very fast complementary bipolar process. The AL1210 is  
packaged in a 16-pin SOIC in order to keep the pin inductances  
and capacitances to a minimum.
