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 SHM-14 for accuracy and speed over the full military temperature range. The droop rate is a low ±2mV/s and can be further reduced by adding an optional external hold capacitor. The 30mA output current and guaranteed specifications for a 100W load provide high drive capability. Operating from ± 5V supplies, the SHM-14 consumes only 250mW of power.
The SHM-14 is built using a fast complementary bipolar process. The device is available in both military and industrial temperature ranges. The SHM-14 is packaged in a 16-pin plastic SOIC or in a 20-pin ceramic LCC.
