... This board can be used as a stand-alone evaluation board or in conjunction with the EVAL-CONTROL BRD2 for evaluation/ demonstration purposes. 2 This board allows control and communicate with all Analog Devices evaluation boards ending in the CB designators. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection ...

DEFINITION OF SPECIFICATIONS INTEGRAL NONLINEARITY ERROR (INL) Integral Nonlinearity is the maximum deviation of a straight line drawn through the transfer function of the actual ADC. The deviation is measured from the middle of each code. DIFFERENTIAL NONLINEARITY ERROR (DNL) ...

AD7675 During the acquisition phase for ac signals, the AD7675 behaves like a one-pole RC filter consisting of the equivalent resistance . The resistors R+ and R– are typically 684 Ω R+, R–, and C S and are lumped components ...

Care should also be taken with the reference temperature coeffi- cient of the voltage reference which directly affects the full-scale accuracy if this parameter matters. For instance, a ± 15 ppm/°C tempco of the reference changes the full scale by ...

AD7675 t 9 RESET BUSY DATA CNVST Figure 12. RESET Timing For other applications, conversions can be automatically initi- ated. If CNVST is held low when BUSY is low, the AD7675 controls the acquisition phase and then automatically initiates a ...

SERIAL INTERFACE The AD7675 is configured to use the serial interface when the SER/PAR is held high. The AD7675 outputs 16 bits of data, MSB first, on the SDOUT pin. This data is synchronized with the 16 clock pulses provided ...
Page 16
AD7675 In read-after-conversion mode, unlike in other modes, it should be noted that the signal BUSY returns low after the 16 data bits are pulsed out and not at the end of the conversion phase, which results in a longer ...

External Clock Data Read During Conversion Figure 20 shows the detailed timing diagrams of this method. During a conversion, while both CS and RD are low, the result of the previous conversion can be read. The data is shifted out, ...

... The decoupling capacitor should be close to the ADC and connected with short and large traces to minimize parasitic inductances. Evaluating the AD7675 Performance A recommended layout for the AD7675 is outlined in the evalu- ation board for the AD7675. The evaluation board package includes a fully assembled and tested evaluation board, docu- mentation, and software for controlling the board from a PC via the Eval-Control BRD2 ...
