HI, ADuCM360 can select internal reference (1.2V) or external reference (~AVDD).When I select internal reference, ADC input voltage ranges are ±VREF@G=1, ±500mV@G=2, ±250mV@G=4, ...and external...
View ArticleRe: AD9826 strange waveform
The source impedance seems too high to drive the AD9826 switched-capacitor input, and the clamp circuit may not work properly because of its fairly low resistance. Can you try adding a buffer between...
View ArticleRe: AD9364 manually initiated calibrations don't converge (quadrature, cp)
After some trial and error today,the TX Quadrature calibration converges when I set the bandwidth to 10Mhz and force theRx NCO Frequency=Tx NCO Frequency=0.If the bandwidth is set to 1MHz, under the...
