GENERAL DESCRIPTION
The SMP08 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 SMP08 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 7 microseconds. The SMP08’s output swing includes the negative supply in both single and dual supply operation. The SMP08 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 SMP08 ideal for calibration requirements that have previously required an ASIC, or high cost multiple D/A……
