Digital Isolators Dual-Channel Isolators with Integrated DC-to-DC Converter (1/1 Channel Directionality)

The ADuM6210 / ADuM6211 / ADuM6212 represent dual-channel digital isolators featuring isoPower, an integrated, isolated dc-to-dc converter. Leveraging Analog Devices, Inc.'s iCoupler technology, the dc-to-dc converter delivers regulated, isolated power with an adjustable range between 3.135 V and 5.25 V. These isolators accommodate input supply voltages ranging from slightly below the required output to significantly higher values, as detailed in Table 2 for popular voltage combinations and their corresponding power levels.

In low-power, isolated designs, the ADuM6210 / ADuM6211 / ADuM6212 negate the necessity for a separate, isolated dc-to-dc converter. The iCoupler chip-scale transformer technology is utilized for both isolated logic signals and the magnetic components of the dc-to-dc converter. The outcome is a compact, all-encompassing isolation solution.

isoPower employs high-frequency switching elements to transfer power through its transformer. Careful attention must be given to printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 Application Note for recommended board layout practices.

The AD7705 / AD7706?are complete analog front ends for low frequency measurement applications. These 2-/3-channel devices can accept low level input signals directly from a transducer and produce serial digital output. The devices employ a ?-? conversion technique to realize up to 16 bits of no missing codes performance. The selected input signal is applied to a proprietary, programmable-gain front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. The first notch of this digital filter can be programmed via an on-chip control register, allowing adjustment of the filter cutoff and output update rate. The AD7705 / AD7706 devices operate from a single 2.7 V to 3.3 V or 4.75 V to 5.25 V supply. The AD7705 features two fully differential analog input channels; the AD7706 features three pseudo differential input channels. Both devices feature a differential reference input. Input signal ranges of 0 mV to 20 mV through 0 V to 2.5 V can be incorporated on both devices when operating with a VDD of 5 V and a reference of 2.5 V. They can also handle bipolar input signal ranges of ?20 mV through ?2.5 V, which are referenced to the AIN(?) inputs on the AD7705 and to the COMMON input on the AD7706.The AD7705 / AD7706 devices, with a 3 V supply and a 1.225 V reference, can handle unipolar input signal ranges of 0 mV to 10 mV through 0 V to 1.225 V. The devices can accept bipolar input ranges of ?10 mV through ?1.225 V. Therefore, the AD7705 / AD7706 devices perform all signal conditioning and conversion for a 2-channel or 3-channel system. The AD7705 / AD7706 are ideal for use in smart, microcontroller, or DSP-based systems. The devices feature a serial interface that can be configured for 3-wire operation. Gain settings, signal polarity, and update rate selection can be configured in software using the input serial port. The parts contains self-calibration and system calibration options to eliminate gain and offset errors on the part itself or in the system. CMOS construction ensures very low power dissipation, and the power-down mode reduces the standby power consumption to 20 ?W typ. These parts are available in a 16-lead, wide body (0.3 inch), plastic dual in-line package (DIP); a 16-lead, wide body (0.3 inch), standard small outline (SOIC) package; and a low profile, 16-lead, thin shrink small outline package (TSSOP).
