(Taiwan patent no.: 458990)

Description

The ES166 is the analog frond end chip

suitable

for

DMM

with

LC

bridge

measurement function. ES166 provides basic

voltage & current (AC/DC) measurement,

resistance measurement, diode check, fast

continuity

measurement,

frequency

measurement, and duty cycle measurement. By

using ES166 to implement the LC bridge

function, the complicated PCB design is not

necessary. The ES166 is built-in resistor

switches network to provide different ranges

control. It also provides a high performance

integrated circuit to generate sinusoidal signal

with

different

frequency to

measure

the

complex impedance of DUT device. The

ES166 includes a flexible serial interface to

external MCU. The MCU could get the real

part and imaginary part of complex impedance

from

ES166

directly

and

calculates

the

D/Q/ESR/

θ parameter easily with L or C

values. The MCU could get the DMM data

from ES166 by each DMM measurement

function mode also.
