Mixed Signal/Analog

Touchstone Semiconductor announced today the TS9002 dual and the TS9004 quad low power analog comparators plus 1.182-V reference integrated circuits. As an improved, pin-for-pin functional equivalent to the MAX923, the TS9002’s 3.2-µA supply current is 16% lower and its ±0.75% initial accuracy voltage reference is 25% lower in both specifications compared to the MAX923.

Conexant Systems today announced the CX20787, an ultra low-power, I2S audio codec with integrated stereo class-D speaker amplifiers and powerefficient class-G headphone amplifiers. When combined with Conexant’s software algorithms and design support, the CX20787 becomes an ideal turnkey solution for applications that require high-quality audio performance such as tablets, ultrabooks, portable media players, and smartphones.

IR today announced the expansion of its PowIRaudio family of integrated power modules with the introduction of the IR4311M and IR4312M. The 40V IR4311M and IR4312M offer a compact, heatsink-free solution for low power Class D audio applications including tabletop audio systems, active speakers and musical instruments with integrated amplifiers.

TI today unveiled the industry’s first family of fully integrated analog front ends for photometry. The new analog integrated circuits support TI HealthTech's vision for helping engineers design innovative electronics for transforming healthcare worldwide. The AFE44xx family integrates all the front end components and associated timing control circuitry of a typical photometry solution.

Dialog Semiconductor today announced its latest ultra low power audio CODEC, designed to provide full range, high fidelity audio capture and playback to a variety of portable devices and audio accessories. Dialog’s new DA7320 audio CODEC features a programmable Digital Signal Processor to offload audio software from the host processor.

Audience today announced the world’s first Smart Sound Processor, the earSmart eS515. The earSmart eS515 Smart Sound Processor combines the company’s award-winning Advanced Voice processing technology with its first high-performance, low-power audio codec for a best in class voice, speech recognition and multimedia experience on a mobile device.

STMicroelectronics announces a new generation of accurate low-power components enabling greatly improved energy efficiency and faster operation of equipment such as gas sensors, medical devices, safety systems and industrial controls. The TS881 is the first in ST’s new generation of comparators compatible with supply voltages as low as 1.1V over a wide temperature range, enabling longer operating times with smaller batteries.

ROHM Semiconductor has recently announced the development of a digital signal processing IC designed to improve audio quality in devices such as smartphones and car navigation systems through cardioid directivity based on beam-formation technology using two omnidirectional microphones. The BU8332KV-M clarifies the specific direction of sound through beam-formation technology using two omnidirectional microphones.

Cypress today introduced the fully-qualified PSoC 5LP programmable system-on-chip family. The new devices provide unmatched high-performance programmable analog, the best ADCs available on an ARM Cortex-M3-based device, and the flexibility to design custom systems with 80+ pre-verified production-ready Components for the PSoC Creator IDE.

Maxim have revealed that it is now shipping the MAX11166 and MAX11167, the industry's smallest bipolar ±5V, 16-bit analog-to-digital converters. Available in a tiny 9mm2 package, the MAX11166 and MAX11167 are the only 12-pin 16-bit bipolar ADCs to integrate an internal reference with buffer, saving cost and at least 88% board space over competing solutions.
