Hi Steve, At this time, our only recommendation is for you to use the 32-bit version of Matlab. We apologize for any inconvenience. Best regards,Coleman
View ArticleRe: Noise in SAR converters
Hi Bo, As you have noted that the AD7760 can get you a dynamic range of 120dB at data rate of 78ks/s, but at the expense of the higher power. If power and size are constrains in your application, the...
