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. 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 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. 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.
