C&D Technologies is Now Introducing to the Market . . . the Datel SHM-50 Series
High Performance Sample-Hold Amplifier Gives Engineers a Stand-Alone Alternative
o SHM-50 provides a stand-alone Sample-Hold solution
o Fast acquisition time with up to 0.005% accuracy
o Small 8-pin mini-DIP package
o TTL interface
April 2006 - C&D Technologies has introduced a miniature, high-speed, stand-alone, Sample-Hold Amplifier designed to provide highly accurate capture and hold of fast signals and pulses in a wide range of analog signal processing applications such as those found in high-speed, multi-channel, multiple-event pieces of equipment.
The SHM-50 provides an alternative to engineers who have previously only been able to obtain sample-hold functionality integrated within an Analog-to-Digital Converter. With a small-signal bandwidth of 70MHz, it is available in a through-hole or surface-mount 8-pin mini-DIP package. The device is a complete sample-hold circuit containing a precision MOS hold capacitor and a MOSFET switching configuration, resulting in faster switching and excellent feed-through attenuation of -78dB. A TTL interface is also included within the specification.
A FET input amplifier design allows a fast acquisition time of 40 nanoseconds for a 2V step to ±0.01% accuracy, and 50 nanoseconds to ±0.005% - equivalent to 14-bit accuracy. Fast sample-to-hold settling times of typically 30 nanoseconds to ±0.01% are also achieved while maintaining a considerably lower droop rate and an aperture uncertainty of just ±2 picoseconds.
Requiring a supply voltage of ±5V, the SHM-50 has a typical power consumption of 225mW. Operating temperature for the through hole version is 0șC to +70șC, while the SHM-50MM version is suitable for use between -55șC and +125șC.
With lead-times from stock to 6 weeks, the SHM-50 list price is $87.00 with 100 piece pricing in the range of $65.00
