Mixed Signal/Analog

STMicroelectronics has introduced the first two devices in its new family of low-g linear accelerometers, distinguished by small form factor and low power consumption. The feature-rich LIS302 sensors meet the growing demand for smart functionality, such as hard-disk drive protection and motion-controlled operation, in today ’s mobile phones, digital audio players, and laptops.

Analog Devices is introducing the industry’s first quad-channel PMU (parametric measurement unit). The AD5522 combines four independent channels in a space-saving 12 mm × 12 mm TQFP package. Each of the four channels includes on-chip sense resistors for 5 microamp, 20 microamp, 200 microamp and 2 milliamp current ranges.

Analog Devices' latest precision PulSAR ADC is designed to increase the portability of patient and industrial monitors and improve the performance and throughput of automated test equipment and data acquisition systems, Analog Devices' AD7980 1-MSPS (mega-sample per second) 16-bit ADC consumes 80 percent less power and board space than the closest competing 16-bit ADC in its class.

Analog Devices' latest family of octal ADCs are ideal for portable medical devices and ultrasound machines where lower power consumption and smaller board space are critical design considerations. The 10-bit AD9212 and 12-bit AD9222 consume less than 100 mW per channel, yielding savings of as much as 5 to 6W when compared to competitive offerings in ultrasound systems containing up to 512 channels.

The event detect and time stamp features in two ultra small, micropower real-time clock/calendar devices from Intersil operate in both normal and battery mode. With their enhanced security functionality, the RTCs are uniquely suited for a variety of applications ranging from security, warranty monitoring, data collection and recording.

Analog Devices’ ADCMP60x family of rail-to-rail comparators is designed for applications that require high-speed, low power, rail-to-rail swing and high precision. The comparator family supports all prevailing digital output stages—including LVDS (low-voltage differential signaling), CML (current-mode logic) and TTL/CMOS required by applications such as medical instruments, test and measurement, RF (radio frequency) and telecommunicat...

Analog Devices is expanding its portfolio of devices targeted at wireless infrastructure applications with the AD9254 14-bit, 150 MSPS ADC. The device achieves 83-dBc SFDR at 70 MHz while consuming only 430 mW—a claimed 50 percent reduction in power consumption over competing solutions.

Semtech Corp., a leading supplier of analog and mixed-signal semiconductors for communications, portable devices, computers, and industrial equipment, today announced the E7765, the first off-the-shelf quad-pin electronics driver with the performance and differential signal capability required for testing next-generation, high-speed memory devices such as DDR III.

Analog Devices Inc., a global leader in high-performance semiconductors for signal processing applications and market leader in amplifier ICs, today introduced two digitally-programmable instrumentation amplifiers (in-amps) that offer unmatched accuracy and bandwidth, plus the speed and precision needed for advanced industrial and instrumentation applications. These applications, which include test, control and high-speed data acquisition systems...

Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a precision operational amplifier that utilizes an innovative zero-crossover, single-input stage architecture to achieve glitchless rail-to-rail performance. Featuring ultra-low distortion of 0.0006% THD+N, low noise of 4.5nV/rtHz and gain bandwidth of 50MHz, the OPA365 is ideal for a wide variety of single-supply applications found in portable instrumentation, data acquisition, tes...
