DESCRIPTION
The HS9403-8 and 9403-16 provide complete 12-bit
data acquisition functionality in a single, 62-pin
package. The 9403 includes 8- or 16-channel
multiplexing, a programmable gain instrumentation
amplifier, sample-hold circuit, 10V buffered
reference, 12-bit 10^sec A /D and three-state output
buffers.
The 9403 is flexible enough to accept full scale input
ranges from ± 10 mV to ± 10V . Three-state output
buffers allow output data to be accessed in any
combination of three 4-bit bytes. Expansion to 32
single-ended or 16 differential inputs can be achieved
with the addition of only 2 ICs.

The 9403 is packaged in a 62-pin, hermetically-sealed,
ceramic package. Temperature ranges available are
0ºC to 70ºCfor commercial versions and –55ºC to
125ºC with M IL-STD-883C screening for military
grades.
