GENERAL DESCRIPTION
DATEL’s SHM-4860 is a high-speed, highly accurate sample-
hold amplifier designed for precision, high-speed analog signal
processing applications. Manufactured using modern, high-
quality hybrid technology, the SHM-4860 features excellent
dynamic specifications including a maximum acquisition time of
only 200ns for a 10V step to ±0.01%. Sample-to-hold settling
time, to ±0.01% accuracy, is 100ns maximum with an aperture
uncertainty of ±50ps.
The SHM-4860 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.
