GENERAL DESCRIPTION

DATEL’s 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.
