-- Digitizes analog sensors output -- 8-bit accuracy -- Miniature surface mount device
IRVINE, Calif., July 20, 2006 (PRIMEZONE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of analog and mixed signal integrated circuits, has announced a new SMBus to analog interface device that digitizes analog signals for use with digital microprocessors.
Designated the LX1800, the new device can be teamed with Microsemi ambient light sensors to incorporate microprocessor-controlled digital dimming of backlight lamps in LCD displays. It also is targeted for audio volume control, digital regulator control, and video control interface applications.
"The LX1800 provides a valuable addition to our portfolio of lighting power management tools, as well as offering a simple solution for other applications needing to convert analog signals for microprocessor control functions," said Paul Bibeau, Sr. Vice President and General Manager of Microsemi's Integrated Products Group. "We expect it to be used by many of our customers who are implementing digital control of ambient light sensors into their designs."
The LX1800 contains an 8-bit ADC, an 8-bit DAC and a fully compliant standard serial data SMBus interface in a single package, designed for use in feedback control system applications.
It has an internal band gap reference, and also allows the use of an external reference. The external reference can be used as an analog input for display brightness control or audio volume control using the DAC, or to provide a wider range of operation for higher amplitude analog signals.
The LX1800, which comes in an 8-pin MLP package measuring only 3mm square, is available for immediate sampling. Technical information is available on the Microsemi web site, http://www.microsemi.com. Samples can be ordered through this site, or from Microsemi sales representatives and authorized distributors. In 10K lot quantities, the unit price for the LX1800 is $0.95.
