Features
8mm (0.31") Digit Height
200mV Full Scale Reading
150uA @ 7.5 to 14V
Auto-zero and Auto-polarity
Selectable Decimal Points
The OEM 1B uses the latest miniaturisation techniques to produce a very compact 3½ digit LCD voltmeter. It is designed to be a drop-in component in most medium and high volume applications, ranging from personal instrumentation and integral sensor indicators to measurement probes. The meter features 8mm (0.31") digit height, 3 decimal points, auto-polarity, auto-zero, 200mV full scale reading and a very low current consumption. Connection to the module is via two rows of pins.
This is a popular part, normally stocked in high quantity and suitable for new designs.
