GENERAL DESCRIPTION
DATELâs SHM-49 is a high-speed, highly accurate sample/hold
designed for precision, high-speed analog signal processing
applications. The SHM-49 features excellent dynamic specifi-
cations including a maximum acquisition time of only 200
nanoseconds for a 10V step to ±0.01%.
Sample-to-hold settling time, to ±0.01% accuracy, is 100
nanoseconds maximum with an aperture uncertainty of ±25
picoseconds.
The SHM-49 is a complete sample/hold circuit, containing a
precision MOS hold capacitor and a MOSFET switching
configuration which results in faster switching and better
feedthrough attenuation. Additionally, a FET input amplifier
design allows faster acquisition and settling times while
maintaining a considerably lower droop rate.
