SHM-49

® ® SHM-49 Miniature, High-Speed ±0.01% Sample-Hold Amplifiers INNOVATION and EXCELLENCE FEATURES Small 8-pin DIP 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 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 ±25 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.
