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 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 100Ω load 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.
