The AD7303 is a dual, 8-bit voltage out DAC that operates from a single +2.7 V to +5.5 V supply. Its on-chip precision output buffers allow the DAC outputs to swing rail to rail. This device uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with QSPI, SPI, microwire and digital signal processor interface standards. The serial input register is sixteen bits wide; 8 bits act as data bits for the DACs, and the remaining eight bits make up a control register.The on-chip control register is used to address the relevant DAC, to power down the complete device or an individual DAC, to select internal or external reference and to provide a synchronous loading facility for simultaneous update of the DAC outputs with a software LDAC function.The low power consumption of this part makes it ideally suited to portable battery operated equipment. The power consumption is 7.5 mW max at 3 V, reducing to less than 3 µW in full power-down mode.The AD7303 is available in an 8-pin plastic dual in-line package, 8-lead SOIC and microSOIC packages.

The ADXL367 is an ultralow power, 3-axis microelectromechanical systems (MEMS) accelerometer that consumes only 0.89 ?A at a 100 Hz output data rate and 180 nA when in motion-triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL367 does not alias input signals by undersampling, but samples the full bandwidth of the sensor at all data rates.The ADXL367 always provides 14-bit output resolution. 8-bit formatted data is offered for more efficient single-byte transfers when a lower resolution is sufficient. 12-bit formatted data is also provided for ADXL362 design compatibility. Measurement ranges of ?2 g, ?4 g, and ?8 g are available, with a resolution of 0.25 mg/LSB on the ?2 g range.In addition to its ultralow power consumption, the ADXL367 has many features to enable true system level power reduction. It includes a deep multimode output first in, first out (FIFO), a built-in micropower temperature sensor, an internal analog-to-digital converter (ADC) for synchronous conversion of an additional analog input with interrupt capability, single-tap and double-tap detection that can operate at any output data rate with only an added 35 nA of current, and a state machine to prevent a false triggering. In addition, the ADXL367 has provisions for external control of the sampling time and/or an external clock.The ADXL367 operates on a wide 1.1 V to 3.6 V supply range, and can interface, if necessary, to a host operating on a separate supply voltage. The ADXL367 is available in a 2.2 mm ? 2.3 mm ? 0.87 mm package.APPLICATIONS 24/7 Always on sensing Industrial Digital Healthcare Prosumer Hearing aids Vital signs monitoring devices Motion-enabled power save switches Motion-enabled metering devices Smart watch with single-cell operation Smart homes

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.
