Description

ES51945 is an integrated analog-to-digital

converter (ADC) with dual 5,000-count LCD

display, which 4-digit main-display (AC/DC

Voltage) and 4-digit sub-display (AC/DC

Current), automatic range selection, and 3V

DC power supply. ES51945 could be

designed for a clamp-meter with V & A

measurement simultaneously. Automatic

range selection is provided for voltage

*Resistance measurement: 500.0Ω – 50.00MΩ

*Frequency counter with duty cycle display:

500.0Hz – 50.00MHz

5% – 95% (< 10kHz)

• ZERO function for DCA mode

• Voltage high crest factor detection

(Taiwan patent no.: 234661)
