Figure 1. Simpliﬁed Block Diagram

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.
