The ADXL346 Development Board is an easy-to-use tool designed to shorten application development time by providing a ready-to-use platform for data collection and firmware development. The board is pre-configured as a datalogger that can be used to gather data for refining algorithms, tuning thresholds, and generally familiarizing oneself with accelerometer data. Powered by two AAA batteries, the board is completely untethered and integrates seamlessly into portable applications. Logged data is stored on a MicroSD memory card, providing essentially unlimited memory capacity and operating system versatility. Data is stored in a text (.txt) file, so no software installation is required to operate the board or read data. A 2GB MicroSD card and a USB MicroSD card reader are provided with the board. Additionally, the board is fully programmable, providing a hardware platform on which firmware can be tested in parallel with development of application hardware. Communications and processing are performed by an ARM7-based ADuC7024 micro-controller, and firmware is written in C. A programming cable is provided with the board, and a development environment and header files are supplied on this page. Finally, the platform can be duplicated in the final application, having already been tested with the application firmware. Schematics and layout can be found under the Supporting Documentation tab and can be used freely in your application. Note that this board is not configured to display real-time data. For real-time evaluation of the ADXL346, please refer to the Inertial Sensor Evaluation Board. For a simple ADXL346 Breakout Board, refer to the EVAL-ADXL346Z.

It comes in a 24-terminal land grid array (LGA) package and provides high isolation and low insertion loss from 100 MHz to 30 GHz.This broadband switch requires dual-supply voltages, +3.3 V and ?3.3 V, and provides complementary metal-oxide semiconductor (CMOS)/low voltage transistor-transistor logic (LVTTL) logic-compatible control.Applications Test instrumentation Microwave radios and very small aperture terminals (VSATs) Military radios, radars, and electronic counter measures (ECMs) Broadband telecommunications systems

The ADRF6821 is a highly integrated, dual radio frequency (RF) input, zero intermediate frequency (IF)/low IF RFIC receiverwith a quadrature demodulator, digital step attenuator (DSA),IF linear amplifiers, an integrated, fractional-N phase-locked loop (PLL), and a low phase noise, multicore, voltage controlled oscillator (VCO). The RFIC is ideally suited for communication digital predistortion (DPD) systems.The high isolation 2:1 RF switch and on-chip wideband RFbalun enable the ADRF6821 to support two single-ended, 50 ? terminated RF inputs. A programmable attenuator ensures anoptimal differential RF input level to the high linearity demodulatorcore. The integrated attenuator offers an attenuation range of 15 dB with a step size of 1 dB. High linearity IF amplifiers follow the demodulator and provide an interface to the next componentin the chain, typically an analog-to-digital converter (ADC).The ADRF6821 offers two alternatives for generating thedifferential local oscillator (LO) input signal: internally viathe on-chip fractional-N synthesizer with low phase noiseVCOs or externally via a low phase noise LO signal. Theintegrated synthesizer enables continuous LO coverage from 450 MHz to 2800 MHz. The PLL reference input supports awide frequency range and includes integrated reference dividers before the phase frequency detector (PFD).When selected, the output of the internal fractional-N synthesizeris applied to a divide by 2, quadrature phase splitter. From theexternal LO path, a 2? LO signal can be used with the divide by 2,quadrature phase splitter to generate the quadrature LO inputs to the mixers.The ADRF6821 is fabricated using an advanced silicon germanium(SiGe), bipolar complementary metal oxide semiconductor(BiCMOS) process. It is available in a 56-lead, RoHS compliant,8 mm ? 8 mm LFCSP package with an exposed pad. Performanceis specified over the ?40?C to +105?C case temperature range.Applications Cellular W-CDMA/GSM/LTE DPD receivers? Microwave, point to point radios

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 ?g/?, 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 LTC2499 is a 16-channel (eight differential), 24-bit, No Latency ??? ADC with Easy Drive technology and a 2-wire, I2C interface. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2499 includes a high accuracy, temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 16 analog input channels operating in single-ended or differential modes) or its internal temperature sensor. The integrated temperature sensor offers 1/30th?C resolution and 2?C absolute accuracy. The LTC2499 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion, after a new channel is selected, is valid. Access to the multiplexer output enables optional external amplifiers to be shared between all analog inputs and auto calibration continuously removes their associated offset and drift.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control

The LTC1068 product family consists of four monolithic clock-tunable filter building blocks. Each product contains four matched, low noise, high accuracy 2nd order switched-capacitor filter sections. An external clock tunes the center frequency of each 2nd order filter section. The LTC1068 products differ only in their clock-to-center frequency ratio. The clock-to-center frequency ratio is set to 200:1 (LTC1068-200), 100:1 (LTC1068), 50:1 (LTC1068-50) or 25:1 (LTC1068-25). External resistors can modify the clock-to-center frequency ratio. High performance, quad 2nd order, dual 4th order or 8th order filters can be designed with an LTC1068 family product.
