Analog Devices, Inc. (ADI) introduced the first in a new series of iCoupler® digital isolators that offers a total bandwidth of 10 Gigabits per second. The ADN4624 digital isolator provides four channels at 2.5Gbps, allowing data to transfer seamlessly in the electrical domain and enabling new system architectures in digital health, instrumentation, and smart industry. The new digital isolator streamlines design and easily integrates isolation for safety or data integrity. The ADN4624 is a compact solution that meets medical standards and reliably isolates high fidelity video and imaging links, precision analog front ends, and serial interconnects as an alternative to cumbersome and specialized fiber solutions.

The LTC3337 is a nanopower primary (non-rechargeable) cell State-of-Health (SoH) monitor with precision coulomb counter, designed to be placed in series with a primary battery with minimal associated series voltage drop. The patented infinite dynamic range coulomb counter tallies all accumulated battery discharge and stores it in an internal register accessible via an I2C interface. Quiescent current consumption is only 100nA, increasing battery run time.

The LTC3337 integrates additional SoH variable monitoring which measures and reports via I2C: battery voltage, battery impedance, and temperature. To accommodate a wide range of primary battery inputs, the peak input current limit is pin selectable from 5mA to 100mA. This enables the IC to present the battery with a load profile which allows it to deliver its maximum capacity, independent of the actual load. This is “battery friendly” and prolongs the lifetime of the cell. The LTC3337 is ideal for primary cell applications that require only occasional power such as applications in remote locations, electronic door locks, or glass break detectors. The device may also be used in rechargeable battery cell applications.

LTC3337 Key Features:

  • Battery Input Voltage Range: 1.8V to 5.5V
  • 100nA Quiescent Current
  • 8 Primary Battery Peak Input Current Limits:
    • 5mA/10mA/15mA/20mA/25mA/50mA/75mA/100mA
  • SoH Monitor for Primary Battery
    • Integrated Coulomb Counter (Q) Additional Monitors for Battery Voltage (V), Battery Impedance (Z), and Temperature (T)

ADI EagleEyeTm ADSW4000 PeopleCount 

The ADI EagleEyeTm ADSW4000 PeopleCount algorithm for people detection and count in indoor spaces such as meeting rooms or office cubicles. The ADSW4000 is the first in a series of application-level software algorithms forming part of the ADI EagleEye platform that includes a hardware subsystem based on ADI’s Blackfin® embedded digital signal processor (DSP) and a set of application-level software building blocks enabling users to quickly develop their own people counting system. The ADSW4000 algorithm provides system edge node analytics that unlock insights to improve space utilization, people safety through distance monitoring, and energy efficiency of spaces within intelligent buildings.
