CAPACITOR GROUND +5V SUPPLY +5V SUPPLY ANALOG OUTPUT GENERAL DESCRIPTION The SHM-12 is an extremely high-speed and accurate monolithic sample-and-hold amplifier designed for fast data acquisition applications. The SHM-12 is accurate (±1LSB at 12 bits over the full military temperature range) and is very fast (10ns and 15ns acquisition times to accuracies of 10 and 12bits, respectively). With this high performance and a full power bandwidth of 55MHz, the SHM-12 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 ±0.5mV/µs. The 30mA output current and guaranteed specifications for a 100Ω load provide high drive capability. Operating from ...
