The ADM1168 Super Sequencer® is a configurable supervisory/ sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems.The device also provides up to eight programmable inputs for monitoring undervoltage faults, overvoltage faults, or out-of-window faults on up to eight supplies. In addition, eight programmable outputs can be used as logic enables. Six of these programmable outputs can also provide up to a 12 V output for driving the gate of an NFET that can be placed in the path of a supply.The logical core of the device is a sequencing engine. This state machine-based construction provides up to 63 different states. This design enables very flexible sequencing of the outputs based on the condition of the inputs.A block of nonvolatile EEPROM is available that can be used to store user-defined information and may also be used to hold a number of fault records that are written by the sequencing engine defined by the user when a particular fault or sequence occurs.The ADM1168 is controlled via configuration data that can be programmed into an EEPROM. The whole configuration can be programmed using an intuitive GUI-based software package provided by Analog Devices, Inc.For more information about the ADM1168 register map, refer to the AN-721 Application Note.APPLICATIONS Central office systems Servers/routers Multivoltage system line cards DSP/FPGA supply sequencing In-circuit testing of margined supplies

The ADXL346 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C® digital interface.The ADXL346 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes of less than 1.0°.Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. Orientation detection is capable of concurrent four- and six-position sensing and a user-selectable interrupt on orientation change for 2D or 3D applications. These functions can be mapped individually to either of two interrupt output pins. An integrated, patent pending memory management system with 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption.Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.The ADXL346 is supplied in a small, thin, 3 mm × 3 mm × 0.95 mm, 16-lead, plastic package.APPLICATIONS Handsets Medical instrumentation Gaming and pointing devices Industrial instrumentation Personal navigation devices Hard disk drive (HDD) protection

The SSM2375 is a fully integrated, high efficiency, Class-D audioamplifier. It is designed to maximize performance for mobilephone applications. The application circuit requires a minimumof external components and operates from a single 2.5 V to 5.5 Vsupply. It is capable of delivering 3 W of continuous output powerwith 100 dB.Spread-spectrum pulse density modulation (PDM) is used toprovide lower EMI-radiated emissions compared with otherClass-D architectures. The inherent randomized nature ofspread-spectrum PDM eliminates the clock intermodulation(beating effect) of several amplifiers in close proximity.The SSM2375 includes an optional modulation select pin(ultralow EMI emissions mode) that significantly reduces theradiated emissions at the Class-D outputs, particularly above100 MHz. In ultralow EMI emissions mode, the SSM2375can pass FCC Class B radiated emission testing with 50 cm,unshielded speaker cable without any external filtering.The device also includes a highly flexible gain select pin thatallows the user to select a gain of 0 dB, 3 dB, 6 dB, 9 dB, or12 dB. The gain selection feature improves gain matchingbetween multiple SSM2375 devices within a single applicationas compared to using external resistors to set the gain.The SSM2375 has a micropower shutdown mode with a typicalshutdown current of 20 nA. Shutdown is enabled by applyinga logic low to the SD pin.The device also includes pop-and-click suppression circuitry.This suppression circuitry minimizes voltage glitches at theoutput during turn-on and turn-off, reducing audible noiseon activation and deactivation.Other features that simplify system-level integration of theSSM2375 include input low-pass filtering to suppress out-of-bandDAC noise interference to the PDM modulator and fixed-inputimpedance to simplify component selection across multipleplatform production builds.The SSM2375 is specified over the industrial temperature rangeof −40°C to +85°C. It has built-in thermal shutdown and outputshort-circuit protection.

An added benefit of spread-spectrum Σ-Δ modu-lation is that no synchronization (SYNC) is needed when using multiple Class-D amplifiers. For applications that require long speaker cables (>10 cm), the SSM2380 includes a user-selectable ultralow EMI emissions mode that eliminates the need for EMI filters at the Class-D outputs.The SSM2380 has a micropower shutdown mode with a typicalshutdown current of 20 nA. Shutdown is enabled by applying alogic low to the SD pin or through an optional independent channel soft shutdown via I2C.The device also includes pop-and-click suppression circuitry. Thissuppression circuitry minimizes voltage glitches at the outputduring turn-on and turn-off, reducing audible noise on activationand deactivation.The fully differential inputs of the SSM2380 provides excellentrejection of common-mode noise on the input. Input couplingcapacitors can be omitted if the dc input common-mode voltage isapproximately VDD/2.The SSM2380 is specified over the commercial temperature range(−40°C to +85°C).
