The ADcmXL3021 is a complete vibration sensing system that combines high performance vibration sensing (using micro-electromechanical systems (MEMS) accelerometers) with a variety of signal processing functions to simplify the development of smart sensor nodes in condition-based monitoring (CBM) systems. The typical ultralow noise density (26 μg/√Hz) in the MEMS accelerometers supports excellent resolution. The wide bandwidth (dc to 10 kHz within 3 dB flatness) enables tracking of key vibration signatures on many machine platforms.The signal processing includes high speed data sampling (220 kSPS), 4096 time sample record lengths, filtering, windowing, fast Fourier transform (FFT), user configurable spectral or time statistic alarms, and error flags. The serial peripheral interface (SPI) provides access to a register structure that contains the vibration data and a wide range of user configurable functions.The ADcmXL3021 is available in a 23.7 mm × 27.0 mm × 12.4 mm aluminum package with four mounting flanges to support installation with standard machine screws. This package provides consistent mechanical coupling to the core sensors over a broad frequency range. The electrical interface is through a 14-pin connector on a 36 mm flexible cable, which enables a wide range of location and orientation options for system mating connectors.The ADcmXL3021 requires only a single, 3.3 V power supply and supports an operating temperature range of −40°C to +105°C.ApplicationsVibration analysisCBM systemsMachine healthInstrumentation and diagnosticsSafety shutoff sensing

The ADuC841/ADuC842/ADuC843are complete smart transducer front ends, that integrates a high performance self-calibrating multichannel ADC, a dual DAC, and an optimized single-cycle 20 MHz 8-bit MCU (8051 instruction set compatible) on a single chip.The ADuC841 and ADuC842 are identical with the exception of the clock oscillator circuit; the ADuC841 is clocked directly from an external crystal up to 20 MHz whereas the ADuC842 uses a 32 kHz crystal with an on-chip PLL generating a programmable core clock up to 16.78 MHz.The ADuC843 is identical to the ADuC842 except that the ADuC843 has no analog DAC outputs.The microcontroller is an optimized 8052 core offering up to 20 MIPS peak performance. Three different memory options are available offering up to 62 kBytes of nonvolatile Flash/EE program memory. Four kBytes of nonvolatile Flash/EE data memory, 256 bytes RAM, and 2 kBytes of extended RAM are also integrated on-chip.The parts also incorporate additional analog functionality with two 12-bit DACs, power supply monitor, and a band gap reference. On-chip digital peripherals include two 16-bit Σ-Δ. DACs, a dual output 16-bit PWM, a watchdog timer, a time interval counter, three timers/counters, and three serial I/O ports (SPI, I2C, and UART).On the ADuC812 and the ADuC832, the I2C and SPI interfaces share some of the same pins. For backwards compatibility, this is also the case for the ADuC841/ADuC842/ADuC843.However, there is also the option to allow SPI operate separately on P3.3, P3.4, and P3.5, while I2C uses the standard pins. The I2C interface has also been enhanced to offer repeated start, general call, and quad addressing.On-chip factory firmware supports in-circuit serial download and debug modes (via UART) as well as single-pin emulation mode via theEApin..ApplicationsOptical networking—laser power controlBase station systemsPrecision instrumentation, smart sensorsTransient capture systemsDAS and communications systems
