The ULN2003A 7-way (or ULN2803A 8-way) darlington driver is usually the go-to chip of choice when you need to switch any high current load from a microcontroller’s GPIO. It provides seven darlington driver stages to give low-side switching and even includes seven common-cathode clamp diodes to snub voltage spikes when high inductance loads are used. Texas instruments have recently introduced an alternative...

STMicroelectronics’ has introduced a new digital audio processor with a >100 dB SNR and Dynamic Range. The device can process most digital input formats including 6.1/7.1 channel and 192 kHz, 24-bit DVD-audio and DSD/SACD. When configured in a 5.1 application its additional 2 channels can be...
Texas SimpleLink Family gets New Members
Texas Instruments have added the CC3100 and CC3200 to its range of SimpleLink microcontrollers with built-in Wi-Fi connectivity. Both chips contain completely integrated Wi-Fi functionality with all the necessary protocols implemented in ROM. The 3100 has an interface to connect an external MCU of your choice while the 3200 has an integrated ARM Cortex-M4 microcontroller, completely available for the user application.
New tiny Ultrasonic Microphone
The Knowles Corporation have extended their range of surface mount MEMs (micro-electro-mechanical system) microphones to include a new model sensitive to ultrasonic frequencies. The company anticipate that the SPH0641LU4H-1 sensor will play an important role in the development of gesture control systems used for smartphones, tablets and other mobile devices.
