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%.
maximum with an aperture uncertainty of ±2 picoseconds.
sion MOS hold capacitor and a MOSFET switching confi guration which
results in faster switching and better feedthrough attenuation. Addition-
ally, a FET input amplifi er design allows faster acquisition and settling
times while maintaining a considerably lower droop rate.
