Analog Devices released new single and dual-channel 14-bit high-speed A/D converters. With high speed and high accuracy, the compact, cost-effective and functionally flexible components are effective for use in communications, instrumentation and test and measurement applications. The new converters meet the performance and small size requirements of the latest 3G and 4G multi-standard cellular infrastructure equipment such as CDMA2000, WB-CDMA, LTE, TD-SCDMA and multi-carrier GSM. Other applications include battery-powered, hand-held instruments, scopes and portable medical devices.

NXP Semiconductors introduced the PCA9525 and PCA9605 -- the industry's first no-offset I2C-bus buffers, which enable system designers to isolate capacitance and interface with other bus buffers. These groundbreaking bus buffers use the no-offset scoreboard method to decide signal direction, rather than using a directional pin and relying on offset voltages to control direction and prevent bus latch-up. Significantly, the no-offset devices are interoperable even with static offset or incremental bus buffers, allowing easy design-in regardless of which other devices are on the bus. In addition, NXP has introduced the PCA9646 -- the industry's first fully buffered 4-channel switch with no-offset ports. All devices work to 1 MHz, and the PCA9605 and PCA9646 support Fast-mode Plus (Fm+), which has 10x the normal I2C-bus drive, allowing longer I2C-buses or placement of more devices on the bus.
