The AD582 is a sample-and-hold amplifier consisting of a high performance operational amplifier, a low leakage analog switch and a JFET integrating amplifier – all fabricated on a single monolithic chip. An external holding capacitor, connected to the device, completes the sample-and-hold function.With the analog switch closed, the AD582 functions like a standard op amp; any feedback network may be connected around the device to control gain and frequency response. With the switch open, the capacitor holds the output at its last level, regardless of input voltage.Typical applications for the AD582 include sampled data systems, D/A deglitchers, analog de-multiplexers, auto null systems, strobed measurement systems and A/D speed enhancement.The device is available in two versions: the 'K' specified for operation over the 0 to +70° commercial temperature range and the 'S' specified over the extended temperature range, -55°C to +125°C. All versions may be obtained in either the hermetic sealed, TO-100 can or the TO-116 DIP.Product HighlightsThe specially designed input stage presents a high impedance to the signal source in both sample and hold modes (up to ±12V). Even with signal levels up to ±VS, no undesirable signal inversion, peaking or loss of hold voltage occurs.The AD582 may be connected in any standard op amp configuration to control gain or frequency response and provide signal inversion, etc.The AD582 offers a high, sample-to-hold current ratio: 107. The ratio of the available charging current to the holding leakage current is often used as a figure of merit for a sample and hold circuit.The AD582 has a typical charge transfer less than 2pC. A low charge transfer produces less offset error and permits the use of smaller hold capacitors for faster signal acquisition.The AD582 provides separate analaog and digital grounds, thus improving the device's immunity to ground and switching transients.The AD582 is available in versions compliant with MIL-STD-883. Refer to the Analog Devices Military Products Databook or current AD582/883B data sheet for detailed specifications.
