MSOP Isolators
The world’s smallest isolators, IsoLoop MSOP Isolators can reduce board area by up to
a factor of ten compared to single-channel PDIP isolators.
Like all IsoLoop Isolators, MSOP isolators feature
minimal signal distortion, wide temperature range, and unlimited life. A
“-1” suffix designates
an MSOP. IsoLoop MSOP Isolators are available in
various input, output, and channel configurations.
And, of course, NVE also offers the industry’s broadest
line of best-in-class SOIC, PDIP, narrow-body, and wide-body isolators.
Key MSOP isolator features include:
• 3 mm by 3 mm MSOP-8
• Passive or digital Inputs
• One or two Channels
• CMOS or open-drain outputs
• 150 Mbps (S-Series)
• 125°C (T-Series)
• IEC 61010-1 approved
More than a dozen MSOP isolator part types are currently
in
stock and available for immediate delivery with no minimum order:

Minimizing SPI Board Area
With MSOP Isolators
If your New Year’s resolution is to to redesign minimizing your SPI board area (a common resolution), consider NVE’s unique MSOP isolators.
Isolating Serial Peripheral Interface Bus (SPI) eliminates ground loops between analog and digital sections and improves resolution by reducing noise. NVE’s unique MSOP isolators minimize board area with the smallest possible footprint.
Here’s an illustration of single-channel isolated delta-sigma ADC using MSOP isolators:
Isolated Delta-Sigma ADC With MSOP Isolators
An IL712-1 isolates the data and an IL711-1 isolates the control lines.
The remarkable inter-device delay matching of IsoLoop Isolators allows the use of two chips without sacrificing channel-to-channel skew.
Of course, all four channels could be isolated with a four-channel IL717 wide-body or narrow-body isolator. The wide-body package provides a full 8 mm creepage distance, but the MSOPs are smaller and still IEC 61010-1 approved.
Four-channel isolators minimize chip count, while MSOPs minimize board area:
