Mixed Signal/Analog

Analog Devices’ ADA4937-2 and ADA4938-2 are said to be the industry's first dual differential analog-to-digital converter (ADC) drivers. The new differential drivers enable designers of data acquisition systems in industrial and communications applications to improve system performance by enhancing key ADC performance characteristics, including SFDR (spurious-free dynamic range) and SNR (signal-to-noise ratio). With the industry’s fir...

Linear Technology has introduced the LTC2351-14, a 1.5Msps low-power analog-to-digital converter with six simultaneous sampling differential inputs. Operating from a single 3.3V supply, power dissipation is typically 16.5mW. The LTC2351-14 features six individual sample-and-hold amplifiers, a multiplexer, and a single ADC making this device the ideal choice for multiphase power measurement, multiphase motor control, data acquisition systems, and...

Texas Instruments has introduced a new monolithic, high-linearity quadrature demodulator for direct down conversion applications. The new device reduces the component count of the receive signal chain in 3G base stations by at least 75 percent, compared to superheterodyne architectures. The TRF3710 demodulator improves the RF receive signal chain by integrating all the devices required to go directly from RF to baseband onto one chip. With the ad...

Linear Technology has introduced the LTC2356-14, a 14-bit analog-to-digital converter that communicates via an SPI-compatible serial interface at output rates up to 3.5Msps. The LTC2356-14 operates from a single 3.3V supply, draws only 18mW at the maximum conversion rate, and is available in a tiny 10-pin MSOP package. The LTC2356-14's successive approximation register (SAR) architecture produces a low power ADC with exceptional AC specification...

The AD974x and AD978x families are the latest additions to Analog Devices’ TxDAC® portfolio of digital-to-analogue converters (DACs) optimised for the transmit signal path of communications systems. The new two-channel, high-speed DACs include the AD974x family of 8-, 10,-, 12-, 14-, and 16-bit devices with sample rates up to 250 MSPS (million samples per second) using LVCMOS (low-voltage CMOS) inputs; and the AD978x family of 12-, 14-,...

Avago Technologies has announced what is said to be the industry's first reflective encoder with analog output. Avago's AEDR-8320 high-resolution miniature surface mount (SMT) optical encoder, which provides precise positioning information and direction sensing, is ideal for use in industrial and office automation applications where space is constrained. This new analog reflective encoder is the latest addition to Avago's broad portfolio of minia...

STMicroelectronics has announced two high-accuracy application specific digital temperature-sensor chips, fully compliant with the JEDEC JC42.4 specification, which are intended for monitoring the temperature of the DIMMs used in personal computers.

IDT has announced five new PCI Express (PCIe) switches optimised to solve system I/O connectivity challenges faced by systems requiring both low lane and low port counts in embedded medical, automotive, PC and consumer applications. The devices range from a 3-lane, 3-port switch to an 8-lane, 5-port switch. These products leverage the IDT expertise in high-speed switching and use the PCI Express standard to allow the seamless interconnect of pro...

Avago Technologies has announced a new ambient light sensor with a precise, logarithmic output response over a wide range of lighting conditions. The company is a leading supplier of analog interface components for communications, industrial and consumer applications. The APDS-9007 is the newest addition to Avago's ambient light sensor product family.

Catalyst Semiconductor offers its CAT5114 Digitally Programmable Potentiometer in an 8-lead 2 x 2.5mm TDFN package, making it the world’s smallest non-volatile digital potentiometer. This tiny form factor helps designers further compress board space in today’s ever-shrinking portable products which currently use digital potentiometers in larger packages.
