Two op amp buffers, CMOS switches and a low leakage capacitor create a simple sample/hold circuit. The LT1006 has the ability to speed up response and reduce supply current through pin 8. When sampling the amplifiers are sped up to acquire signals in just 20us. When put into hold mode the supply current is throttled back to only 250uA.
