The CA-IS310X is a highly stable, isolated operational amplifier widely used in power systems. This series of chips in the secondary side of the inheritance of high performance high bandwidth operational amplifier, used to feedback and amplify error signals. The amplified error signal is transmitted to the primary side through the buffered output. The CA-IS310X offers faster response, higher stability, and longer life than the optocoupler.


Ca-is310x also has the characteristic of stable transfer function, that is, it does not change with time and temperature, which is impossible to achieve by traditional optocoupler.

02 High stability



The REFOUT voltage of the device is less than 1mV in the range of -40 °C to 125°C, and the measured voltage is <0.04%. COMP to EAOUT gain changes slightly, measured 1.5%; The gain from EAOUT to EAOUT2 changes slightly, which is less than 0.5%.



3 high precision



REFOUT voltage:


1) The initial error at room temperature shall not exceed 0.5%.


2) -- 40°C to 125°C error no more than 1%.


3) REFOUT2 Connect the positive phase input of the internal operational amplifier to provide accurate reference voltage.



04 wide range



1) Wide operating temperature range, -40 °C to 125°C, suitable for industrial applications.


2) Wide operating voltage range, VDD1 and VDD2 input voltage 3V~20V.


3) The overall bandwidth is 400kHz, suitable for most isolating switching power supply applications.
