Toshiba Corporationfs Semiconductor & Storage Products Company today announced the launch of optical coupled isolation amplifiers with a delta-sigma AD converter that can detect infinitesimal electric current and voltage fluctuation with high-precision, for use in industrial equipment applications.
The new products will be in available in analog output and digital output types, and can be provided in either a low height 2.3mm(max) SO8L thin package or a conventional DIP8 package. Shipment of the new products starts today.

Monitoring the phase current of motors and BUS voltage fluctuations for accurate feedback to the microcontroller is essential to realizing the high-precision operation required in recent industrial equipment, including inverters and servo amplifiers. In order to meet these requirements, the new optical coupled isolation amplifiers are equipped with a high-precision delta-sigma AD converter on the input side and achieve the industryfs highest level of linearity[1], a performance of 0.02%(typ.)@NL200 for the analog output products and 3LSB(typ.)@INL for the digital output products. The isolation amplifiers also secure a CMTI (Common-Mode Transient Immunity) value of 20kV/µs(typ.), enabling stable operation in motor control applications which usually generate high levels of noise. Furthermore, the 5000V(min.) isolation voltage makes them suitable for use in various industrial equipment applications.
Applications:
- Industrial equipment including inverters, servo amplifiers, robots, CNCs and power supplies
- Wind turbine and photovoltaic inverters, battery management
- UPS, power supplies for servers, battery management and air-conditioners for office and residential use
