Description
ES51955 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. ES51955 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,
capacitance measurement, and frequency
counter. Other features include inrush
function, 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.
