GENERAL DESCRIPTION
Pin
ꢀ
Function
DATEL’s SHM-50 is a high-speed, highly accurate sample/hold designed
for precision, high-speed analog signal processing applications. The
SHM-50 features excellent dynamic specifications including a maximum
acquisition time of only 40 nanoseconds for a 2V step to 0.0ꢀ1.
Sample-to-hold settling time, to 0.0ꢀ1 accuracy, is 20 nanoseconds
maximum with an aperture uncertainty of 2 picoseconds.
The SHM-50 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.

All ground pins should be tied together and connected to system analog ground
as close to the package as possible. It is recommended to use a ground plane
under the device and solder ground pins directly to it. Take care to ensure that
no ground potentials can exist between ground pins. A single +5V supply can be
used for both +5V Digital Supply (pin ꢀ) and +5V Analog Supply (pin 7).
External 0.ꢀμF to 4.7μF tantalum bypass capacitors are required in critical
applications.

Gain and offset adjusting can be accomplished using the external circuitry
shown in Figure 2. Adjust offset with a 0V input. Adjust gain with a FS input.
