PRODUCT OVERVIEW
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 fea-
tures 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 cir-
cuit, containing a precision MOS hold capacitor and
a MOSFET switching configuration which results in
faster switching and better feedthrough attenu-
ation. Additionally, a FET-input amplifier design
allows faster acquisition and settling times while
maintaining a considerably lower droop rate.
