PRODUCT OVERVIEW
The SHM-43 sample-hold utilizes a proprietary
architecture in delivering an acquisition time of 35
nanoseconds maximum to 0.01% and 20 nanosec-
onds maximum to 0.1% accuracy.
Operation requires +15V and ±5V supplies and
the analog input range is ±2V. Packaged in a small
14-pin DIP, the SHM-43 offers a CMOS compat-
ible sample command while dissipating just 545
milliwatts.
The SHM-43 has been designed for applica-
tions that demand fast acquisition times (25 nS,
±0.01%), fast hold mode settling (20nS, ±0.01%),
wide bandwidth, and the ability to drive resis-
tive (100Ω), and capacitive (50 pF) loads with no
compromise in performance. These features make
the SHM-43 an ideal choice for driving flash A/D
converters in applications such as radar and com-
munications.
Two temperature ranges are offered: the com-
mercial 0 to+70 ˚C and military -55 to +125 ˚C.
