Sichuan earth microelectronics ca-is1300 isolated operational amplifier for current detection is on the market

Chuantu microelectronics CA-IS1300G25G Isolated operational amplifier for current detection New products are coming ！

01 Product overview

CA-IS1300 It is a high-precision isolated operational amplifier optimized for current detection based on shunt resistance . Low offset and gain errors and associated temperature drift can maintain measurement accuracy over the full operating temperature range .

The device uses silicon dioxide （SiO2） As a barrier , Support compliance UL1577 Certified up to 5 kVRMS Electrical isolation of . This technology separates the high and low voltage regions to prevent the devices in the low voltage region from being damaged , At the same time, it provides low radiation and high magnetic field immunity . High common mode transient immunity （CMTI） signify CA-IS1300 The device transmits signals correctly between the isolation layers , Suitable for high voltage 、 Industrial motor control and drive applications of high-power switches . The device internal input common mode overvoltage protection and high side power loss detection functions are helpful for fault diagnosis and system safety .
