Indeed, 40 lbs is then maximum with these weights.Figure 4. Successive-approximation ADC algorithm using balance scale and binary weights.The overall accuracy and linearity of the SAR ADC are determined primarily by the internal DAC’s characteristics. Early precision SAR ADCs, such as the ...
[答:Jing] you can use ADC"s INL and DNL parameter to evaluate the non-linearity and you can also use ENOB parameter to check code loss. Thanks!Generally ENOB releated with ADC"s SNR [2006-2-28 10:32:08] [问:吉星] 在差分输入时,不考虑直流,使用差分放大器和变压器哪个更好. ...
The BGA package of the AD4030-24 integrates all critical power supply and reference bypass capacitors, reducing the footprint and system component count, and lessening sensitivity to board layout. AD4030-24主要特性: ► High performance ► Throughput: 2 MSPS maximum ► INL: ±0.9 ppm maximu...

Several prescalers allow the application to configure AHB and APB domain clock frequencies, 64 MHz at maximum. 3.10 General-purpose inputs/outputs (GPIOs) Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-...
Turn on both power supplies, and verify +1.20V across test points TP4 and TP5 with a voltmeter. If necessary, adjust potentiometer R34 to obtain +1.20V. Enable the function generators. Set the clock function generator to its maximum output amplitude (999mV for the suggested HP8662A) and a...
