SHM-49 Miniature, High-Speed, Complete ±0.05% Sample Hold Amplifiers SMT Package FEATURES Small 8-pin DIP or SMT package 200ns max. acquisition time to ±0.01% 100ns max. sample-to-hold settling time to ±0.01% 16MHz small signal bandwidth 74dB feedthrough attenuation ±25 picoseconds aperture uncertainty 415mW maximum power dissipation INPUT/OUTPUT CONNECTIONS GENERAL DESCRIPTION DATEL’s SHM-49 is a high-speed, highly accurate sample/hold designed for precision, high-speed analog signal processing applications. The SHM-49 features excellent dynamic specifications including a maximum acquisition time of only 200 nanoseconds for a 10V step to ±0.01%. Sample-to-hold settling time, to ±0.01% accuracy, is 100 nanoseconds maximum with an aperture uncertainty of ±2 picoseconds. The SHM-49 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.

DATEL, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1151 USA 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. 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. The maximum capacitive load to avoid oscillation is typically 250pF. Recommended resistive load is 500Ω, although values as low as 250Ω may be used. Acquisition and sample-to-hold settling times are relatively unaffected by resistive loads down to 250Ω and capacitive loads up to 50pF. Greater load capacitances will affect both acquisition and settling time. 5. 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. • Tel: (508) 339-3000 • www.datel.com • e-mail: [email protected] 23 Jul 2015 MDC_SHM-49.C01 Page 2 of 3 SHM-49 Miniature, High-Speed, Complete ±0.05% Sample Hold Amplifiers ANALOG INPUT (GAIN ADJUST) R1 10kΩ, 0.1% 10kΩ, 0.1% 50Ω TO SHM-49 PIN 3 5.11kΩ HIGH-SPEED FAST-SETTLING AMPLIFIER 3MΩ –15V +15V R2 (OFFSET ADJUST) Figure 2.
