16-Channel, 12-Bit D ata Acquisition System
H S9403
D ata Converter Line
FEATURES
• M ultiplexer, instrumentation amp, S/H, A /D and
control logic in a 62-pin package
• Three state output buffer
• Instrumentation amp with selectable gain
ranging 1 to 1,0 0 0
• Single-ended (-16) and differential (-8) inputs
• 50 kHz minimum throughput
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 70ºC for commercial versions and –55ºC to
+125ºC with M IL-STD-883C screening for military
g r a d e s.
