ADC-based: digitally-isolated: wide-input: 16-channel: AC/DC binary input reference design
This reference design showcases a cost-optimized and scalable ADC-based AC/DC binary input module (BIM) architecture with reinforced isolation. The 16 channels of a 10- or 12-bit SAR ADC are used for sensing multiple binary inputs. The op amps: in addition to keeping the cost per-channel low: provide optimal signal conditioning for each input. A digital isolator (basic or reinforced) is used to isolate the host MCU or processor. A provision is available to measure temperature: humidity: and magnetic field for diagnostics. A reinforced isolation DC/DC power supply with configurable output provides the required supply for the binary module.

Reference design for I<sup>2</sup>C range extension: I<sup>2</sup>C to CAN
This reference design focuses on extending I2C range from on-board to off-board through transmission cables using CAN transceivers and then converting the signal back to I2C. This approach allows for better signal integrity due to the differential signaling of the CAN transceivers. The differential signals allow for better EMI rejection: lower power: less concern of different ground potentials between boards: and the capability to use termination compared to extending the I2C lines using solely I2C buffers.

Isolated Current Sense with Integrated Shunt Resistor and I<sup>2</sup>C Interface Reference Design
This verified design can accurately measure current on a bus that carries hundreds of volts. This design is targeted for solar and server applications due to their wide high-voltage input range requirements. This design uses the INA260 current shunt monitor with integrated shunt resistor for current measurements: two P82B96 bidirectional buffers to facilitate I2C communication: and the ISOW7842 to allow isolated current measurements. The INA260 is limited by a common-mode voltage of 36 V; using the ISOW7842 allows the designer to float the INA260 side of the design to facilitate higher bus voltages.
