... SIP or DIP style package. The primary distinction between the AD202 and the AD204 is that the AD202 is powered directly from supply while the AD204 is powered by an externally supplied clock, such as the recommended AD246 Clock Driver. The AD202 and AD204 provide total galvanic isolation between the input and output stages of the isolation amplifier through the use of internal transformer-coupling ...

... 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. Although the AD202/AD204 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... The primary distinction between the AD202 and AD204 is in the method by which they are powered: the AD202 operates directly from while the AD204 is powered by a non- isolated externally-supplied clock (AD246) which can drive AD204s. The main advantages of using the externally- clocked AD204 over the AD202 are reduced cost in multichannel applications, lower power consumption, and higher bandwidth ...

... V supply. Alternatively, the circuit shown in Figure 4 (essentially an AD246) can be used. In either case, one clock circuit can operate at least 32 AD204s at the rated minimum supply voltage of 14.25 V and one additional isolator can be operated for each 40 mV increase in supply voltage ...

... For these of F isolators, the significant resistance will normally be that the path from the source of the common-mode signal to IN COM. The AD202 and AD204 also perform well in applications requiring rejection of fast common-mode steps, as described in the Appli- cations section. 180 160 ...

... Figure 12. The filter limits the bandwidth of the input (to about 5.3 kHz) so that the isolator does not see fast, out-of-band input terms that can cause small amounts (± 0.3%) of internal ringing. The AD204 will then settle to ± 0.1% in about 300 microseconds for step. 3.3k V ...

... AD204s can be driven from a single AD246 (or equi- valent) clock driver when the isolated power outputs of the AD204s are loaded with less than 200 µA each worst-case supply voltage of 14 ...

... In such cases, shielded cable may be required or AD204s can be used. APPLICATIONS EXAMPLES Low-Level Sensor Inputs. In applications where the output of low-level sensors such as thermocouples must be isolated, a low drift input amplifier can be used with an AD204, as shown 39k ...

... Floating Current Source/Ohmmeter. When a small floating current is needed with a compliance range ± 1000 V dc, the AD204 can be used to both create and regulate the current. This can save considerable power, since the controlled current does not have to return to ground. In Figure 21, an AD589 reference is used to force a small fixed voltage across R ...
