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 performance- 2. 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 associ- ated data converter. 4. The offset, pedestal, and gain errors of the SHM-43 are laser trimmed at DATEL and no external compensation capabilities have been provided. This prevents introducing noise through the offset adjust terminals of the S/H amplifi er and guarantees excellent galn linearity, offset drift, and pedestal performance.
