Description:
The ES51977 is an integrated analog-
to-digital converter (ADC)with 3 3/4 digits
and 42-segment bargraph LCD display,
automatic range, and 3V battery power
supply.
Automatic range selection is provided
for voltage (AC/DC) measurement, ohm
measurement, current(uA and mA)
measurement, and frequency counter. The
ES51977 also provides serial data output
function.
Expensive and bulky mechanical range
switches are not required. The other
functions are provided for data holding,
low battery detection, auto-power-off,
diode measurement, continuity checking.
