Content	DMS-30LCD Series 3½ Digit, LCD Display Digital Panel Voltmeters www.murata-ps.com/dpmemail: sales@murata-ps.com 06 Jan 2011 MPM_DMS30LCD.D02 Page 2 of 6 TECHNICAL NOTES Performance/Functional Speciﬁ cations Typical at TA = +25°C and supply voltage = +5V (using the single-ended input circuit) or +9V (using the differential input circuit), unless otherwise noted. ➀ Applies for transient or continuous overvoltages applied to (+) INPUT HI (pin 11) with (–) INPUT LO (pin 12) properly connected. Pin 12 is not overvoltage protected (see Figure 1). Voltages applied to pin 12 should not exceed the supply voltage. ➁ Listed spec applies to 5V-powered models only. For 9V-powered models, both (–) INPUT LO (pin 12) and (+) INPUT HIGH (pin 11) must always be at least 1.5V above –BATTERY (pin 3) and at least 1.5V below +BATTERY (pin 1). ➂ See Technical Notes.

Leave blank for standard models. Add B for backlit models. Power Source: 5 = +5V 9 = +9V 1. +1.23V REFERENCE OUTPUT (Pin 9): This pin is the output of the meter’s precision +1.23V internal reference, and it is referenced to ANALOG COMMON (pin 10) which sits at a potential of approximately +2V. This output should be buffered if used to drive external loads since sourcing more than 15µA from pin 9 can affect both the initial accuracy and temperature drift of the meter. 2. ANALOG COMMON (Pin 10): This pin is connected to an internal, low-noise, “relative” ground. It is used in certain differential and “ﬂ oat- ing” measurements as described in the Applications section of this data sheet and Ap Note 3 of the DATEL Panel Meter Catalog. Pin 10 should not be connected to pin 3 (5V RETURN/–BATTERY) or to your system’s analog ground.
