  
Full-scale input range from 50mV to 10V  
  
Three-state outputs  
  
16 S.E. or 8 differential input channels  
  
Auto-sequencing channel addressing

GENERAL DESCRIPTION  
Internal HDAS circuitry includes:  
Using thin and thick-film hybrid technology, DATEL offers complete low-cost  
data acquisition systems with superior performance and reliability.  
  
Analog input multiplexer (16 S.E. or 8 diff.)  
  
Resistor-programmable instrumentation amplifier  
The HDAS-8 (with 8 differential input channels) and the HDAS-16 (with  
16 single-ended input channels) are complete, high-performance, 12-bit  
data acquisition systems in 62-pin SMT or DIP packages. Each HDAS may  
be expanded up to 32 single-ended or 16 differential channels by adding  
externalmultiplexers.  
  
Sample-and-hold circuit complete with MOS hold capacitor  
  
10 Volt buffered reference  
  
12-bit A/D converter with three-state outputs and control logic  
Internal channel address sequencing is automatic after each conversion,  
or the user may supply external channel addresses.
