component-like convenience and outstanding reliability, DMS-40LCD Series 4½ Digit DPM’s

provide the ultimate combination of price, precision and convenience. These miniature

(2.17” x 0.92” x 0.43”) digital voltmeters combine an advanced, autozeroing A/D converter,

a precision reference circuit and a large (0.4”/10.2mm high), easy-to-read LCD display in a

single, fully encapsulated, 12-pin DIP package. All models incorporate a built-in bezel and

are easily mounted in either panels or pc boards.

display. Input impedance is a minimum 800kΩ, and CMRR is typically 86dB (dc to 60Hz).

CMV is ±2V, and all models are overvoltage protected to ±250V (on their non-inverting

inputs).

ing 3.5mA max.) or a single 9V supply/battery (drawing 2.5mA max.). All models feature

autopolarity changeover and overrange indication. A display HOLD function is standard on

all non-backlit models.

ibrated A/D converters, DMS-40LCD meters are able to withstand the harshest environ-

ments and never require adjustment or calibration. Plug-in convenience, long-term stability

and wide operating temperature range (0 to +50°C) make DMS-40LCD meters the right

solution for any high-accuracy DPM requirement.

APPLICATIONS 2. Differential Input Conﬁgurations: Differential measurements can be made with either 5V-powered or 9V-powered meters. Figure 3, though not a practical real-world application, uses a voltage divider to demon- strate the concept of a differential input signal. Be careful ...

APPLICATIONS 5. Process Control (4-to-20mA) Measurements: In many common process-control applications, a 4-to-20mA current loop is used to transmit information. Because DMS-40LCD meters have such high input impedance, a simple shunt resistor across the meter’s input can be used to ...
