FEATURES
PRODUCT OVERVIEW
35 nSec maximum acquisition time to 0.01%
The SHM-43 sample-hold utilizes a proprietary
architecture in delivering an acquisition time of 35
nanoseconds maximum to 0.01% and 20 nanoseconds 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 compatible sample command while dissipating just 545
milliwatts.
The SHM-43 has been designed for applications that demand fast acquisition times (25 nS,
30 nSec maximum hold-mode settling to 0.01%
1 pSec aperture uncertainty
150 MHz small-signal bandwidth
545 mW power dissipation
Small 14-pin DIP package
CMOS control signal
±0.01%), fast hold mode settling (20nS, ±0.01%),
wide bandwidth, and the ability to drive resistive (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 communications.
Two temperature ranges are offered: the commercial 0 to+70 ˚C and military -55 to +125 ˚C.

TECHNICAL NOTES
1.
Bypass the ±5V analog, +5V digital, +15V supplies with a 1μF, 25V tantalum capacitor in parallel with a O.O1
μF ceramic capacitor mounted as close to the pin as possible.
To achieve optimum performance2.
Additional bypass capacitors are necessary, because of internal high switching speeds, and high slew rates of
internal components. REF BYPASS (pin 2), +5 BYPASS (pin 9), and -5 BYPASS (pin 10) are internal connections
that must be bypassed with a minimum 1μF tantalum capacitor mounted as close to the pin as possible. The
polarity of the connections are shown on the test circuit drawing, Figure 2.
3.
As with all high speed analog circuits, it is essential that good grounding tcehniques be used. Tie all ground
pins together at a single ground point beneath the device, and use a short low impedance run to the ground of
the analog power supplies. The ground point should be a solid ground plane under the device and any associated data converter.
4.
The offset, pedestal, and gain errors of the SHM-43 are laser trimmed at Murata Power Solutions (DATEL)
and no external compensation capabilities have been provided. This prevents introducing noise through the
offset adjust terminals of the S/H amplifier and guarantees excellent galn linearity, offset drift, and pedestal
performance.
