TYPICAL APPLICATIONS (continued)
*See Figure 48 to select R value DB7 = “1” for VIN(+)>VIN(−)+(VREF/2). Omit circuitry within the dotted area if
hysteresis is not needed.
Figure 27. µP Compatible Differential-Input Comparator with Pre-Set VOS (with or without Hysteresis)
*Beckman Instruments #694-3-R10K resistor array
Figure 28. Handling ±10V Analog Inputs
Figure 29. Low-Cost, µP Interfaced, Temperature-to-Digital
Converter
*Circuit values shown are for 0°C ≤ TA ≤ +128°C
**Can calibrate each sensor to allow easy replacement, then A/D can be calibrated with a pre-set input voltage.
