500 MSPS Direct Digital Synthesizer with 10-Bit DAC

GENERAL DESCRIPTION The AD9911 is a complete direct digital synthesizer (DDS). This device includes a high speed DAC with excellent wideband and narrowband spurious-free dynamic range (SFDR) as well as three auxiliary DDS cores without assigned digital-to-analog converters (DACs). These auxiliary

Switch-mode LED Driver IC with High Current Accuracy

General Description The HV9911 is a current mode control LED driver IC designed to control single switch PWM converters (buck, boost or buck-boost), in a constant frequency or constant off-time mode. The controller uses a peak current control scheme, (with programmable slope compensation), and
