Maximizing SFDR Performance in the GSPS ADC: Spur Sources and Methods of Mitigat
Texas InstrumentsThe SFDR performance of an ADC is limited by the largest spur in the spectrum from DC to Fs / 2. These spurs can either be reduced or avoided entirely for maximum SFDR performance based on the application. This reference design explores the reason behind spurs in the 10-bit and 12-bit GSPS ADCfamily. The specific products covered are: ADC12D1800RF ADC12D1600RF ADC12D1000RF ADC12D800RF ADC12
DRV91680 EVM Sensored Software Guide
Texas InstrumentsTI's DRV91680 and DRV91690 are three-phase brushless DC (BLDC) motor controllers and predrivers. Only requiring external FETs, they are integrated solutions providing necessary analog and digital peripherals to create a robust motor solution. Having a programmable MSP430 core, the DRV91680 and DRV91690 are capable of controlling both sensored and sensorless motors by simply downloading the respective application code. This guide describes the application code for sensored motor control using Hall-effect sensors.
AN-2128 ADC1xD1x00 Pin Compatibility (Rev. C)
Texas InstrumentsIn order to facilitate upgrading applications from a 10-bit Gig ADC to a 12-bit Gig ADC the ADC10D1x00(ADC10D1500/ADC10D1000) is designed to be pin-compatible with the ADC12D1x00(ADC12D1800/1600/1000). This means that a single board layout may be designed with both resolutionADCs in mind for more cost efficient and time-to-market product development.
