The ADuM4221/ADuM4221-1/ADuM4221-2are 4 A isolated, half bridge gate drivers that employ the Analog Devices, Inc.,iCoupler®technology to provide independent and isolated high-side and low-side outputs. The ADuM4221/ADuM4221-1/ADuM4221-2 provide 5700 V rms isolation in an increased creepage wide body, 16-lead SOIC_IC. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers.The isolators operate with a logic input voltage ranging from 2.5 V to 6.5 V, providing compatibility with lower voltage systems. In comparison to gate drivers employing high voltage level translation methodologies, the ADuM4221/ADuM4221-1/ADuM4221-2 offer the benefit of true, galvanic isolation between the input and each output.The ADuM4221/ADuM4221-1/ADuM4221-2 each have built in overlap protection and allow dead time adjustment. A single resistor between the dead time pin (DT) and the GND1pin sets the dead time on the secondary side between the high-side and the low-side outputs.An internal thermal shutdown (TSD) sets outputs low if the internal temperature on the ADuM4221/ADuM4221-1/ADuM4221-2 exceeds the TSD temperature. As a result, the ADuM4221/ADuM4221-1/ADuM4221-2 provide reliable control over the switching characteristics of the insulated gate bipolar transistor (IGBT)/metal-oxide semiconductor field effect transistor (MOSFET) configurations over a wide range of positive or negative switching voltages.ApplicationsSwitching power suppliesIsolated IGBT/MOSFET gate drivesIndustrial invertersGallium nitride (GaN)/silicon carbide (SiC) compatible1Protected by U.S. Patents 5,952,849; 6,873,065; 7,075,239.

The ADuM7701 is a high performance, second-order, Σ-Δ modulator that converts an analog input signal into a high speed, single-bit data stream, with on-chip digital isolation based on Analog Devices, Inc.,iCoupler® technology. The device operates from a 4.5 V to 5.5 V power supply range (VDD1) and accepts a pseudo differential input signal of ±250 mV (±320 mV full-scale). The pseudo differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required.The analog input is continuously sampled by a high performance analog modulator and converted to a ones density digital output stream with a data rate of up to 21 MHz. The original information can be reconstructed with an appropriate sinc3 digital filter to achieve an 86 dB signal-to-noise ratio (SNR) at 78.1 kSPS with a 256 decimation rate and a 20 MHz main clock. The serial input and output operates from a 5 V or a 3 V supply (VDD2).The serial interface is digitally isolated. High speed complementary metal-oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, results in the on-chip isolation providing outstanding performance characteristics, superior to alternatives such as optocoupler devices.
