Q.series - ADC Method
The Q.bloxx modules support precise analog measurements by means of a 24-bit Sigma Delta A/D converter. The integrating nature of this method of A/D conversion allows for extremely stable conversion with a high noise rejection. While this method has long been the preferred method for high accuracy data logging, it is not necessarily the most effective method for the high speed dynamic response required in closed loop systems for control applications.
When high speed closed loop control is important, the Q.bloxx A102 and A106 provide analog inputs and outputs on a single Q.bloxx module. This allows measurement signals to be handled with 100 kHz updates, using a 19 bit successive approximation A/D conversion. Q.bloxx modules provide the choices for the best in system performance.
