Instrumentation amplifier enables very high accuracy

Instrumentation amplifier enables very high accuracy
Expanding its instrumentation amplifier portfolio, Microchip Technology has introduced the MCP6N16. This zero-drift device features a self-correcting architecture which maximises DC performance by enabling ultra-low offset, low offset drift, and superior common-mode and power-supply rejection, while eliminating the adverse effects of 1/f noise.

Regulator offers 95% efficiency & 3MHz switching

Regulator offers 95% efficiency & 3MHz switching
The LTC3124, a 3MHz, current-mode, synchronous boost DC/DC converter, has been introduced by LinearTechnology. Featuring output disconnect and inrush current limiting, the dual-phase converter minimises component size while delivering lower output ripple, versus an equivalent single-phase device. The device's internal 2.5A per phase capable switches together to deliver 5A of switch current.

Thyristor stack controller makes retrofitting easy

Thyristor stack controller makes retrofitting easy
An external thyristor stack controller, called the PLXD, has been introduced by Sprint Electric. Supplied with the latest field bus protocols, the controller can be designed into a new installation or easily retrofitted to an existing thyristor power stack where the control electronics need updating or require adding into a field bus topography network.
