The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 ?A at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of ?2 g, ?4 g, and ?8 g are available, with a resolution of 1 mg/LSB on the ?2 g range. For applications where a noise level lower than the normal 550 ?g/?Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 ?g/?Hz typical) can be selected at minimal increase in supply current.In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate. A pin output is provided to directly control an external switch when activity is detected, if desired. In addition, the ADXL362 has provisions for external control of sampling time and/or an external clock.The ADXL362 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL362 is available in a 3 mm ? 3.25 mm ? 1.06 mm package.APPLICATIONS Hearing aids Home healthcare devices Motion enabled power save switches Wireless sensors Motion enabled metering devices

The AD4114 is a low power, low noise, 24-bit, sigma-delta (?-?) analog-to-digital converter (ADC) that integrates an analog front end (AFE) for eight fully differential or 16 single-ended, high impedance (?1 M?), bipolar, ?10 V voltage inputs.The AD4114 integrates key analog and digital signal conditioning blocks to configure eight individual setups for each analog input channel in use. The AD4114 features a maximum channel scan rate of 6.21 kSPS (161 ?s) for fully settled data.The embedded 2.5 V, low drift (?5 ppm/?C), band gap internal reference (with output reference buffer) reduces the external component count.The digital filter allows flexible settings, including simultaneous 50 Hz and 60 Hz rejection at a 27.27 SPS output data rate. The user can select different filter settings depending on the requirements of each channel in the application. The automatic channel sequencer enables the ADC to switch through each enabled channel.The precision performance of the AD4114 is achieved by integrating the proprietary iPassives? technology from Analog Devices, Inc. The AD4114 is factory calibrated to achieve a high degree of specified accuracy.The AD4114 operates with a single power supply that allows simplified use in galvanically isolated applications. The specified operating temperature range is ?40?C to +105?C. The AD4114 is housed in a 40-lead, 6 mm ? 6 mm LFCSP.ApplicationsProgrammable logic controller (PLC) and distributed control system (DCS) modules Instrumentation and measurement

The SSM2167 is a complete and flexible solution for conditioning microphone inputs in personal electronics and computer audio systems. It is also excellent for improving vocal clarity in com-munications and public address systems. A low noise voltage controlled amplifier (VCA) provides a gain that is dynamically adjusted by a control loop to maintain a set compression characteristic. The compression ratio is set by a single resistor and can be varied from 1:1 to over 10:1 relative to the fixed rotation point. Signals above the rotation point are limited to prevent overload and to eliminate popping. A downward expander (noise gate) prevents amplification of background noise or hum. This results in optimized signal levels prior to digitization, thereby eliminating the need for additional gain or attenuation in the digital domain. The flexibility of setting the compression ratio and the time constant of the level detector, coupled with two values of rotation point, make the SSM2167 easy to integrate in a wide variety of microphone conditioning applications.The device is available in a 10-lead MSOP package, and is guaranteed for operation over the extended industrial temperature range of ?40?C to +85?C.ApplicationsDesktop, portable, or palmtop computersTelephone conferencingCommunication headsetsTwo-way communicationsSurveillance systemsKaraoke and DJ mixers

The AD5172 / AD5173 are dual-channel, 256-position, one-time programmable (OTP) digital potentiometers that employ fuse link technology to achieve memory retention of resistance settings. The digital potentiometer, VR, and RDAC terms are used interchangeably. OTP is a cost-effective alternative to EEMEM for users who do not need to program the digital potentiometer setting in memory more than once. These devices perform the same electronic adjustment function as mechanical potentiometers or variable resistors but with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.TheAD5172 / AD5173 are programmed using a 2-wire, I2C-compatible digital interface. Unlimited adjustments are allowed before permanently setting the resistance value. During OTP activation, a permanent blow fuse command freezes the wiper position (analogous to placing epoxy on a mechanical trimmer).Unlike traditional OTP digital potentiometers, the AD5172 / AD5173 have a unique temporary OTP overwrite feature that allows for new adjustments even after a fuse is blown. However, the OTP setting is restored during subsequent power-up conditions. This allows users to treat these digital potentiometers as volatile potentiometers with a programmable preset.APPLICATIONS Systems calibration Electronics level setting Mechanical trimmers replacement in new designs Permanent factory PCB setting Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Gain control and offset adjustment
