Description::
ISO 1001 isolation amplifier IC integrates
a high isolated DC/DC power supply and a
high-powered isolated amplifier. It also
provides a group of isolated dc power
supply and two 5V base voltage supply for
use of exterior circuit extending, like
electric bridge circuit and other circuits.
Input and output isolated voltage is
3000VAC.ISO-1001 Isolation Amplifier
IC is very easy to use; just a few external
components are required.

Application Note:
Figure 2 is the typical connection figure for ISO-1001 isolated
amplifier. Input and output amplifier are following mode.
Isolated amplifier is magnified 10 times.
R1, R2 & W1 is zero circuit

R1=2K, R2=5.1K, W1=2K
Connection Figure
Assistant power supply is +12VDC
Input amplifier design:
Input amplifier circuit is as Figure 3, when input(Pin1 COM)is 0.5V, output is 5V( pin13 and 14 short )
Input Reverse Amplifier Circuit:
The design of input Reverse amplifier is as Figure 4, Kin = - R11/R12, R3 = R11//R12
For example: when Vin is 0~-100mV,output is 0~5V:
R11=50K R12=10K R13=8.3K Kin=-50/10=-5
Input In-phase Amplifier Design:
The design of input in-phase amplifier is as Figure 5 Kin=1+R2/R1
For example: when Vin is 0~+100Mv, output is 0~5V:
R11=51K R12=10K R13=10K Kin=1+39.9/10=4.99
In Figure 4 and Figure 5, R11 can be replaced by a potentiometer series connecting with a
resistance to getwww.szsunyuan.com

Input Amplifier Design:
SY-FG01 is the design of an output amplifier for the users (see Figure 6), FB is the
reversing input end
of the amplifier. When Pin 13 connected to Pin 14, the output amplifying multiples
Kout=1+33/10=4.3.
Due to some parts of Isolation Amplifier have already had an amplifying multiple of 2.35,
the total
amplifying multiple shall be K=4.3*2.35=10.1.
When the voltage in the COM end of input amplifier is lower than 0.5v, the amplifying
multiple can be
adjusted by output amplifier (see Figure 7), W2 is within the range of 1~100K.
