Initially targetin...

Texas Instruments has announced the ADS795x family of low power, precision SAR analog-to-digital converters (ADC) in a small form factor. These devices provide excellent linearity and AC performance for high-density applications and are optimized to deliver maximum performance in battery and low-voltage applications, such as handheld medical instruments, programmable logic controllers and digital power supplies.

Maxim Integrated Products has introduced the MAX19505/MAX19506/MAX19507, a pin-compatible family of dual-channel, 8-bit, 65/100/130Msps ADCs. Offering the industry's lowest power consumption, the devices consume a mere 43mW (MAX19505), 57mW (MAX19506), and 74mW (MAX19507) of analog power per channel. Additionally, these ADCs achieve nearly ideal 8-bit dynamic performance, with a 49.8dBFS SNR and 69dBc SFDR at 70MHz.

Analog Devices has developed a new motion sensing device specifically for energy-constrained portable consumer products. The ADXL345 three-axis digital iMEMS (integrated micro-electro-mechanical system) accelerometer is the lowest-power device in its class, achieving an 80 percent power savings compared to competing three-axis inertial sensors. The ADXL345 also incorporates an on-chip ADC (analog-to-digital converter) that simplifies hardware con...

Intersil has introduced the ISL54406, a highly integrated, ultra-low distortion stereo audio switch which eliminates unwanted clicks and pops typically caused by powering up and down, muting on and off, and switching between audio sources. The combination of audio performance and reduction in external components makes the ISL54406 the ideal choice for compact MP3 players, docking speaker systems, cell phones, portable DVD players and sound cards...

Linear Technology has introduced the LTC2631, a family of pin- and software-compatible 12-bit, 10-bit and 8-bit DACs in a tiny TSOT-23 package, making it the smallest I2C DAC family with an internal reference on the market today. DACs in such small packages are ideal for fine tuning bias voltages in applications such as optical networking and RFID systems. The LTC2631 makes the integrated 10ppm/°C reference output available to drive the referenc...

Wolfson has introduced the WM8351 and WM8352 integrated power management and audio ICs to extend its family of Smart Power devices. Both the devices are highly integrated solutions that guarantee high performance audio and power management in support of a wide range of multimedia processors and usage scenarios.

Analog Devices has introduced the AD8275 level-translating ADC (analog-to-digital converter) driver, which simplifies signal conditioning for high-voltage industrial and instrumentation designs. System designers now can use a single component to attenuate, level-shift, and drive low-voltage ADCs in high-voltage applications, reducing part count and board space by simplifying the signal conditioning complexities that often occur in data acquisit...

Analog Devices has introduced a pair of four-channel 12-bit analog-to-digital converters (ADCs) that use 50 percent less printed-circuit-board surface area than other ADCs in their class. The AD9239 and AD9639 quad analog-to-digital converters require only eight pins and traces, compared to as many as 26 in competing dual-channel devices, which yields space savings in high-speed signal processing applications, including cable infrastructure and p...

Analog Devices has unveiled what it says is the industry’s lowest noise, widest bandwidth family of continuous-time sigma-delta (CTSD) analogue-to-digital converters (ADCs) today. The 16-bit, AD9261 and AD9262 CTSD converter, and the AD9267 CTSD modulator couple low noise and high dynamic range with a bandwidth of up to 10 MHz.
