| SHM-43 High-Speed, 0.01% Hybrid Sample/Hold Typical unit FEATURES 35 nSec maximum acquisition time to 0.01% 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 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 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, 0.01%), fast hold mode settling (20nS, 0.01%), wide bandwidth, and the ability to drive resistive (100), 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 1F, 25V tantalum capacitor in parallel with a O.O1 F ceramic capacitor mounted as close to the pin as possible. 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 1F tantalum capacitor mounted as close to the pin as possible. The polarity of the connections are shown on the test circuit drawing, Figure 2. 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. 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.
