TSL2740 - Light, Ambient Sensor Evaluation Board

MSP-TS430PM64F - MSP430 64-pin FRAM Target Socket Board (Microcontrollers not included)

The TAS2521 is a low power digital input speaker amp with support for 24-bit digital I2S data mono playback.

In addition to driving a speaker amp up to 4-Ω, the device also features a mono headphone driver and a fully programmable miniDSP for signal processing. The digital audio data format is programmable to work with popular audio standard protocols (I2S, left/right-justified) in master, slave, DSP and TDM modes. The fully programmable miniDSP can support several functions such equalization for audio, multi-band DRC, tone generation and several other user defined functions. An on-chip PLL provides the high-speed clock needed by the digital signal-processing block. The volume level can be controlled by register control. The audio functions are controlled using the I2C™ serial bus or SPI bus. The device includes an on-board LDO that runs off the speaker power supply to handle all internal device analog and digital power needs. The included POR as power-on-reset circuit reliably resets the device into its default state so no external reset is required at normal usage; however, the device does have a reset pin for more complex system initialization needs. The device also includes two analog inputs for mixing and muxing in both speaker and headphone analog paths.

KSZ8091RNA Ethernet PHY Interface Evaluation Board

The AD7402 is a high performance, second-order, ?-? modulator that converts an analog input signal into a high speed, single-bit data stream, with on-chip digital isolation based on Analog Devices, Inc., iCoupler? technology. The AD7402 operates from a 4.5 to 5.5 V (VDD1) power supply and accepts a differential input signal of ?250 mV (?320 mV full scale). The differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required.The analog input is continuously sampled by a high performance analog modulator, and converted to a ones density, digital output stream with a data rate of 10 MHz. The original information can be reconstructed with an appropriate digital filter to achieve 87 dB signal to noise ratio (SNR) at 39 kSPS. The serial input/output can use a 3 V to 5.5 V or a 3.3 V supply (VDD2).The serial interface is digitally isolated. High speed complementary metal oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, means the on-chip isolation provides outstanding performance characteristics, superior to alternatives such as optocoupler devices. The AD7402 device is offered in an 8-lead wide body SOIC package and has an operating temperature range of ?40?C to +105?C.Safety and regulatory approvals UL recognition 5000 V rms for 1 minute per UL 1577 CSA Component Acceptance Notice 5A VDE Certificate of Conformity DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 VIORM = 1250 VPEAKApplications Shunt current monitoring AC motor controls Power and solar inverters Wind turbine inverters Data acquisition systems Analog-to-digital and opto-isolator replacements
