CAPACITOR GROUND +5V SUPPLY +5V SUPPLY ANALOG OUTPUT GENERAL DESCRIPTION The SHM-14 is an extremely high-speed and accurate monolithic sample-and-hold amplifier designed for fast data acquisition applications. The SHM-14 is accurate (±0.5 LSB to 14-bits over the full military temperature range) and is very fast (10ns and 20ns acquisition times to accuracies of 10 and 12 bits respectively). With this high performance and a full power bandwidth of 70MHz, the SHM-14 is an ideal device for driving flash and high-resolution subranging A/D converters. A careful design optimizes the device for accuracy and speed over the full military temperature range. The droop rate is a low ±2mV/µs and can be further reduced by adding an optional external hold capacitor. The 30mA output current and guaranteed specifications for a 100Ω load provide high drive capability. Operati...
