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 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 seven microseconds. The SMP04 can operate from single or dual power supplies with TTL/CMOS logic compatibility. Its output swing includes the negative supply.
The SMP04 is ideally suited for a wide variety of sample-and- hold applications including amplifier offset or VCA gain adjustments. One or more can be used with a single or multiple DACs to provide multiple setpoints within a system.
The SMP04 offers significant cost and size reduction over lent module or discrete designs. It is available in a 16-pin hermetic or plastic DIP and surface mount SOIC packages. It is specified the extended industrial temperature range of 0°C to +85°C.
