ES51970(6000counts)

DMM Analog front end with Inrush

Description

Features

ES51970 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. ES51970 provides voltage &

current (AC/DC) measurement, resistance

measurement, capacitance measurement,

diode/continuity measurement, frequency

measurement, duty cycle measurement and

inrush current measurement mode. The

ES51970 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.
