GENERAL DESCRIPTION
Murata Power Solution’s SHM-950 is a high-speed, highly accurate
sample/hold designed for precision, high-speed analog signal process-
ing applications. The SHM-950 features excellent dynamic specifications
including a maximum acquisition time of only 800 nanoseconds for a
10V step to ±0.001%.
Sample-to-hold settling time, to ±0.001% accuracy, is 200 nanosec-
onds maximum with an aperture uncertainty of ±25 picoseconds.
The SHM-950 is a complete sample/hold circuit, containing a preci-
sion MOS hold capacitor and a MOSFET switching configuration which
results in faster switching and better feedthrough attenuation. Addition-
ally, a FET input amplifier design allows faster acquisition and settling
times while maintaining a considerably lower droop rate.
