The AD5820BCBZ-REEL7 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 AD5820BCBZ-REEL7 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 AD5820BCBZ-REEL7 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.
