GENERAL DESCRIPTION

SW  
The SMP18 is a monolithic octal sample-and-hold; it has eight  
internal buffer amplifiers, input multiplexer, and internal hold  
capacitors. It is manufactured in an advanced oxide isolated  
CMOS technology to obtain high accuracy, low droop rate, and  
fast acquisition time. The SMP18 has a typical linearity error of  
only 0.01% and can accurately acquire a 10-bit input signal to  
±1/2 LSB in less than 2.5 microseconds. The SMP18’s output  
swing includes the negative supply in both single and dual sup-  
ply operation.

SMP18  
The SMP18 was specifically designed for systems that use a  
calibration cycle to adjust a multiple of system parameters. The  
low cost and high level of integration make the SMP18 ideal for  
calibration requirements that have previously required an ASIC,  
or high cost multiple D/A converters.  
The SMP18 offers significant cost and size reduction over  
discrete designs. It is available in a 16-pin plastic DIP, a  
narrow body SO-16 surface-mount SOIC package or the thin  
TSSOP-16 package. The SMP18 is a higher speed direct  
replacement for the SMP08.  
The SMP18 is also ideally suited for a wide variety of sample-  
and-hold applications including amplifier offset or VCA gain ad-  
justments. One or more SMP18s can be used with single or  
multiple DACs to provide multiple set points within a system.
