GENERAL DESCRIPTION

CH OUT

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.
