excellent stability (±0.15 counts/°C). All models operate from a single +5V supply, and the
low-power models draw as little as 10mA (50mW total power). A DISPLAY TEST function is
standard on each device.

The circuit of Figure 2 avoids problems normally associated with ground-loop currents. Separate ground runs should be used for 5V RETURN (pin 3) and (–) INPUT LO (pin 12). This will ensure that large LED currents will not fl ...

... APPLICATIONS 2. Differential Input Confi gurations: Differential measurements can be made with all DMS-30PC meters. Figure 3, though not a practical real-world application, uses a voltage divider to demonstrate the concept of a differential input signal. Be careful not to exceed the ±2V common mode voltage limitation for 5V-powered meters. ...

... The low-power, red LED DMS-30PC-2-RL can be confi gured to allow power supply monitoring over the range of 4.5-18Vdc. The circuit in Figure 8 uses a low-drop-out, three-terminal regulator (LM- 2931Z-5, available from National Semiconductor) to provide regulated 5V power to the meter ...
