H S9403 16-Channel, 12-Bit D ata Acquisition System 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 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 grades. 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.
