The ADuM1240 is a micropower, dual-channel default high digital isolator with 2/1 directionality based on the Analog Devices, Inc., iCoupler® technology (Quad-channel products available). Combining high speed CMOS andmonolithic air core transformer technologies, these isolationcomponents provide outstanding performance characteristicssuperior to alternatives, such as optocoupler devices, yet require the lowest power of any available isolation product.
Packaged in an 8-lead SOIC, this series of quad, 3 kV digital isolationdevices operate with supplies as low as 2.5 V, offering thelowest available power consumption at a fraction of the power of comparable isolators at comparable data rates (up to 2 Mbps). In addition, all models provide low pulse width distortion (<8 ns for A grade) and an input glitch filter for extraneous noise disturbance protection.
All models operate with the supply voltage on either sideranging as low as 2.25 V, providing compatibility with lowervoltage systems, as well as enabling voltage translationfunctionality across the isolation barrier. All products also havean output default logic state in the absence of the input power.When power is first applied, or is not yet applied to the inputside, the ADuM1240 and ADuM1241 have a default highoutput and the ADuM1245 and ADuM1246 have a default lowoutput.
Product Highlights
- Outstanding Power Performance. These 3 kV digital
isolators operate with 2.5 V supplies. - Distortion and Noise Protection. Low pulse width
distortion (< 8 ns for A grade models) and an input glitch
filter for extraneous noise disturbance protection.
iCoupler Technology. Patented Analog Devices technology combining high speed CMOS and monolithic air core transformer technologies.
Applications
- General-purpose, low power, multichannel isolation
- 1 MHz low power SPI
- 4 mA to 20 mA loop process control
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
