Digital Potentiometer /Rheostat with Incremental Encoder and SPI Interface
GENERAL DESCRIPTION:
LS7190, LS7191, 7192, LS7193, LS7194 and LS7195 are versions of a three terminal digital potentiometer. Quadrature clocks from an incremental encoder or non-quadrature up and down clocks are applied to the A and B inputs.
LS9100X Direct-AC LED Driver IC
The X010-10P0L-30 is a complete and thoroughly integrated evaluation board that features the LS9100X direct-AC LED driver.
The Archimedes Series is designed to be driven directly off the 120VAC line voltage, eliminating the standard power supply and extending the long-term life of the product. The high-power factor can provide enhanced energy savings to the end application.
The smaller form factor provides significant flexibility in creative fixture design and reduces development time. This all-inclusive solution provides impressive performance for distributed light source applications in conjunction with the quality of light.
This board will simplify your evaluation process and development time by providing you with a premium design ready for testing.
