The MAX22441, MAX22840-MAX22842, and MAX22881 are a family of 4-channel, reinforced, ultra-low-power digital galvanic isolators using Analog Devices proprietary process technology. The MAX22441 is in a 16-QSOP package with a withstand voltage rating of 3kVRMS for 60 seconds, the MAX22840-MAX22842 are in a 16 wide SOIC package with a withstand voltage rating of 5kVRMS for 60 seconds, and the MAX22881 is in a 20-SSOP package with a withstand voltage rating of 3.75kVRMS for 60 seconds. Devices are rated for operation at ambient temperatures from -40°C to +125°C.
The devices transfer digital signals between circuits with different power domains, using as little as 77.04μW per channel at 1Mbps (1.8V supply). The ultra-low-power feature reduces system dissipation, increases reliability, and enables compact designs. Devices are available with a maximum data rate of 10Mbps and with default-high or default-low outputs. The devices feature low propagation delay and low clock jitter, which reduces system latency. Independent 1.71V to 5.5V supplies on each side also make the devices suitable for use as level translators. All four channels of the MAX22840 transfer data in the same direction. Three out of four channels of the MAX22441/841/881 transfer data in one direction while the other one transfers data in the opposite direction. Two channels of the MAX22842 transfer data in one direction and the other two in the opposite direction.
APPLICATIONS
