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
(AC/DC)
measurement,
resistance
measurement, current measurement and
frequency counter. Other features include
offset removing feature for DCA clampmeter,
data holding, duty cycle measurement, diode
measurement, temperature measurement,
continuity checking, multi-level low battery
detection, auto power off, re-power on,
backlight driver, and buzzer output driver.
