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. 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.
