Function
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 specifications including a maximum
acquisition time of only 200 nanoseconds for a 10V step to 0.01ꢀ.
Sample-to-hold settling time, to 0.01ꢀ accuracy, is 100 nanoseconds
maximum with an aperture uncertainty of 2 picoseconds.
The SHM-49 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.

1.
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 logic 1 on S/H puts the unit in the sample mode. A logic 0 puts the unit in hold
mode.
The maximum capacitive load to avoid oscillation is typically 250pF. Recom-
mended resistive load is 500Ω, although values as low as 250Ω may be used.
Acquisition and sample-to-hold settling times are relatively unaffected by
resistive loads down to 250Ω and capacitive loads up to 50pF. Greater load
capacitances will affect both acquisition and settling time.

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. Adjust so
that the output in the hold mode matches the input.
