GENERAL DESCRIPTION The HDAS-524 and HDAS-528 are complete data acquisition systems. Each contains an internal multiplexer, instrumentation amplifier, sample-hold, analog-to-digital converter and three-state outputs. Packaged in miniature, 40-pin, double-dip packages, the HDAS-524/528 have a low power dissipation of 2.6 Watts. The HDAS-524 provides 4 differential inputs, and the HDAS-528 provides 8 single-ended inputs. An internal instrumenta- tion amplifier is characterized for gains of 1, 2, 4, 8, 10 and 100. The gain range is selectable through a single external resistor. HDAS-524/528 OPERATION The HDAS devices accept either 8 single-ended or 4 differential input signals. Tie unused channels to SIGNAL GROUND, pin 14. Channel selection is accomplished using the multiplexer address pins as shown in Table 1. Obtain additional channels by connecting external multiplexers. The acquisition time is the amount of time the multiplexer, instrumentation amplifier and sample-hold require to settle within a specified range of accu- racy. The acquisition time can be measured by how long EOC is low before the rising edge of the START CONVERT pulse for continuous operation. Higher PIN FUNCTION PIN FUNCTION

- Rated performance requires using good high-frequency circuit board layout
prevents contamination of the analog ground by noisy digital ground currents.
- Double-level multiplexing allows expanding the multiplexer channel capacity
