... 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 single-ended or 16 differential channels by adding externalmultiplexers. ...

... ANALOG SIGNAL COMMON, POWER COMMON and DIGITAL COMMON are connected internally. For optimal performance, tie all ground pins (17, 41, 42, 45, 46) directly to a large analog ground plane beneath the package. 8. For HDAS-16, tie pin “signal source common” if possible. Otherwise tie pin 50 to pin 41 (ANA SIG COM). DATEL ® ...

... Offset and gain adjustments are made by connecting two 20k trim potenti- ometers as shown in Figure 2. 2. Connect a precision voltage source to pin 4 (CH0 IN). If the HDAS-8 is used, connect pin 58 (CH0 LOW IN) to analog ground. Ground pin 20 (CLEAR) and momentarily short pin8 (STROBE). Trigger the A/D by connecting pin 7 (EOC) to pin 8 (STROBE) ...

... RGAIN resistor. Table 3 refers to the appropriate RDELAY and RGAIN resis- tors required for various gains. The HDAS devices enter the hold mode and are ready for conversion as soon as the one-shot (controling acquisition time) times out. An internal clock is gated ON, and a start-convert pulse is sent to the 12-bit A/D converter, ...

... As shown in Figure 3, the multiplexer has reversed biased diodes which protect the input channels from being damaged by overvoltage signals. The HDAS input channels areprotected up to 20V beyond the supplies and can be increasedby adding series resistors (Ri) to each channel. The input resistor must limit the current fl owing through the protection diodes to 10mA. ...
