GENERAL DESCRIPTION  
PIN FUNCTION  
PIN  
FUNCTION  
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 12-  
bits, 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 100load provide high drive capability.  
Operating from ±5V supplies, the SHM-12 consumes only  
250mW of power.  
The SHM-12 is built using a fast complementary bipolar  
process. The device is available in both military and industrial  
temperature ranges. The SHM-12 is packaged in a 20-pin  
plastic SOIC or ceramic LCC.
