Power-Efficient Op Amp in Small SC70 Package

   

The MAX9622 op amp features rail-to-rail output and 50MHz GBW at just 1mA supply current.
 
 
At power-up, this device autocalibrates its input offset voltage to less than 100µV. It operates from a single-supply voltage of 2.0V to 5.25V.
The MAX9622 is available in a tiny 2mm x 2mm, 5-pin SC70 package and is rated over the -40°C to +125°C automotive temperature range.

Digi Connect WAN cellular and WiMAX routing gateways provide secure high-speed wireless connectivity to remote sites and devices. 

These products can be used for reliable primary wireless network connectivity to equipment at remote locations, as well as for a backup to existing landline communications.

 

 

Features:

  • Small, cost-optimized cellular routers
  • 2G/2.5G (GSM GPRS/EDGE) models with 1 serial, 1 Ethernet port; for modem replacement in low/medium bandwidth applications
  • 3G (GSM HSUPA/UMTS/CDMA/EV-DO Rev. A PCI express module) models with 1 serial, 1 Ethernet, 1 USB, 1 sensor port; integrated VPN; high-speed upgradeable.
  • Industrial and GSM-R options available
  • Digi Remote Management platform for easy setup, configuration and maintenance and local custom scripting via Python
 

Antenna Companion Modules

   

Trimble's Antenna Companion Modules (ACM's) combine a Trimble GPS receiver with a perfectly matched antenna on an easy to integrate module

 

Key Features:

  • Optimally matched and tuned onboard antenna brings high performance positioning to market faster.
  • Multiple GPS solution options on Silvana and Anapala allow you to choose the best fit for your application.
  • With its external antenna connector and auto-switch, Silvana enables a single flexible product to support multiple applications or installation options.
  • The Zelia ACM integrates the Condor C1011 with a linearly-polarized printed monopole antenna element. It is an omni-directional antenna ideal for portable device applications.
High efficiency embedded GPS antenna suitable for ceramic patch replacement
   
Acuta A10415 is an innovative high performance GPS antenna designed to replace a typical 12x12mm² ceramic patch antenna without compromising performance. A10415 is easily tuned using a simple matching circuit on the host PCB, allowing the same antenna to be used in different devices without physical modifications.
Acuta is intended to be mounted on the edge of the host device PCB, facing the sky, which provides an optimal upward hemispherical right hand circular polarization (RHCP) radiation pattern. The antenna is soldered directly onto the host PCB, without the need of expensive coaxial cables, RF connectors or mounting frames, thereby significantly reducing the total BOM of the GPS solution.
 
APPLICATION NOTES
 

White paper

 

AMR (Automatic Meter Reading) and AMI (Advanced Metering Infrastructure) allow customers to make real-time choices about power utilization. These initiatives also enable utility companies to increase the effectiveness of the regional power grids by managing demand load during peak times and reducing unneeded power generation. This white paper discusses past and current initiatives for AMR and AMI, as well as technology, scalability and deployment, vendor neutrality, security, and manageability of these initiatives
