ES51980(6000counts)

DMM Analog front end with Inrush

Description

Features

ES51980 is an analog frond end chip of

DMM built-in 6000(SADC)/600(FADC)

counts dual ADCs. The SADC is operated at

slower speed for higher resolution. The

FADC is operated at higher speed for lower

resolution. ES51980 provides voltage &

current (AC/DC) measurement, resistance

measurement, capacitance measurement,

diode/continuity measurement, frequency

measurement, duty cycle measurement and

inrush current measurement mode. An analog

switches network is built-in for insulation

resistance application. The ES51980 also

supports multi-level battery detection,

low-pass-filter feature for AC mode and dual

mode measurement for V+F & A+F. A 3-wire

serial bus for MPU I/O port will be used

easily for firmware design. Flexible function

design is supported for different kinds of

DMM or Clamp-on meter application.
