SHM-50 Miniature, High-Speed, Complete ±0.05% Sample Hold Amplifiers .EW 3-40ACKAGE FEATURES Small 8-pin DIP or SMT package 30ns typical acquisition time to ±0.01%, 40ns typical acquisition time to 0.005% 15ns typical sample-to-hold settling time to ±0.01% 100MHz small signal bandwidth –78dB feedthrough attenuation ±2 picoseconds aperture uncertainty 85mW typical, 135mW maximum power dissipation INPUT/OUTPUT CONNECTIONS GENERAL DESCRIPTION Murata Power Solution’s SHM-50 is a high-speed, highly accurate sample/hold designed for precision, high-speed analog signal processing applications. The SHM-50 features excellent dynamic specifications including a maximum acquisition time of only 40 nanoseconds for a 2V step to ±0.01%. Sample-to-hold settling time, to ±0.01% accuracy, is 20 nanoseconds maximum with an aperture uncertainty of ±2 picoseconds. The SHM-50 is a complete sample/hold circuit, containing a precision MOS hold capacitor and a MOSFET switching configuration which results in faster switching and better feedthrough attenuation. Additionally, a FET input amplifier design allows faster acquisition and settling times while maintaining a considerably lower droop rate. –5V SUPPLY 5 Pin 1 2 3 4 5 6 7 8 +5V ANALOG SUPPLY 7 Function +5v Digital Supply S/H Control Analog Input Analog Return –5v Supply Analog Output +5v Analog Supply Power Ground +5V DIGITAL SUPPLY 1 1k 7 1k 7 ANALOG INPUT 3 6 ANALOG OUTPUT S/H CONTROL 2 SWITCH DRIVER For full details go to www.murata-ps.com/rohs 8 POWER GROUND 4 ANALOG RETURN Figure 1.

TECHNICAL NOTES 1. All ground pins should be tied together and connected to system analog ground as close to the package as possible. It is recommended to use a ground plane under the device and solder ground pins directly to it. Take care to ensure that no ground potentials can exist between ground pins. A single +5V supply can be used for both +5V Digital Supply (pin 1) and +5V Analog Supply (pin 7). 2. External 0.1μF to 4.7μF tantalum bypass capacitors are required in critical applications. 3. A logic 1 on S/H puts the unit in the sample mode. A logic 0 puts the unit in hold mode. 4. Gain and offset adjusting can be accomplished using the external circuitry shown in Figure 2. Adjust offset with a 0V input. Adjust gain with a ±FS input. Adjust so that the output in the hold mode matches the input.
