GENERAL DESCRIPTION

The SMP04 is a monolithic quad sample-and-hold; it has four internal precision buffer amplifiers and internal hold capacitors. It is manufactured in ADI’s advanced oxide isolated CMOS technology to obtain the high accuracy, low droop rate and fast acquisition time required by data acquisition and signal processing systems. The device can acquire an 8-bit input signal to ± 1/2 LSB in less than four microseconds. The SMP04 can operate from single or dual power supplies with TTL/CMOS logic compatibility. Its output swing includes the negative supply.
