The ADXL213 is a low cost, low power, complete dual axis accelerometer with signal conditioned, duty cycle modulated outputs, all on a single monolithic IC. The ADXL213 measures acceleration with a full-scale range of ±1.2 g (typical). The ADXL213 can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity).The outputs are digital signals whose duty cycles (ratio of pulse width to period) are proportional to acceleration (30%/g). The duty cycle outputs can be directly measured by a microcontroller without an A/D converter or glue logic.Innovative design techniques are used to ensure high zero g bias stability (typically better than 0.25 mg/°C), as well as tight sensitivity stability (typically better than 50 ppm/°C).The typical noise floor is 160 μg/√, allowing signals below 1 mg (0.06° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (The user selects the bandwidth of the accelerometer usingcapacitors CX and CYM at the XFILT and YFILT pins. Bandwidths of0.5 Hz to 250 Hz may be selected to suit the application.The ADXL213 is available in a 5mm x 5mm x 2mm, 8-pad hermetic LCC package.ApplicationsAutomotive tilt alarmData projectorsNavigationPlatform stabilization/levelingAlarms and motion detectorsHigh accuracy, 2-axis tilt sensing

The DAC8412 / DAC8413 are quad, 12-bit voltage output DACs with readback capability. Built using a complementary BiCMOS process, these monolithic DACs offer the user very high package density.Output voltage swing is set by the two reference inputs VREFH and VREFL. By setting the VREFL input to 0 V and VREFH to a positive voltage, the DAC provides a unipolar positive output range. A similar configuration with VREFH at 0 V and VREFL at a negative voltage provides a unipolar negative output range. Bipolar outputs are configured by connecting both VREFH and VREFL to nonzero voltages. This method of setting output voltage range has advantages over other bipolar offsetting methods because it is not dependent on internal and external resistors with different temperature coefficients.Digital controls allow the user to load or read back data from any DAC, load any DAC, and transfer data to all DACs at one time.An active low RESET loads all DAC output registers to midscale for the DAC8412 and zero scale for the DAC8413.The DAC8412 / DAC8413 are available in 28-lead plastic DIP, 28-lead ceramic DIP, 28-lead PLCC, and 28-lead LCC packages.They can be operated from a wide variety of supply and reference voltages with supplies ranging from single +5 V to ±15 V, and references from +2.5 V to ±10 V. Power dissipation is less than 330 mW with ±15 V supplies and only 60 mW with a +5 V supply.For MIL-STD-883 applications, contact your local Analog Devices, Inc. sales office for the DAC8412/DAC8413/883 data sheet, which specifies operation over the −55°C to +125°C temperature range.
