Mixed Signal & Analogue

While digital electronics tends to get more than its fair share of coverage, analogue electronics remains the technology that makes things happen. It’s the interface between the real world and the 1s and 0s of the digital domain.

The range of technologies falling into the analogue domain is wide; everything from data conversion to amplification to switches. Like electronics in general, analogue products are getting more complex as device developers look to integrate more functionality. Recognising this, manufacturers have started to develop more capable design tools to support engineers.

Because analogue design is so important, New Electronics covers all aspects of the technology regularly.

Analogue front end reference design

As high resolution systems move to higher bit counts, they become more sensitive to noise, making such systems difficult to build and maintain accuracy. Looking to overcome the challenges, Maxim Integrated has launched the MAXREFDES67, a 24bit analogue front end reference design that can accept four signals.

Low noise, low power, high speed 24-bit SAR ADC

Linear Technology has introduced the LTC2380-24, a no latency 24-bit 2Msps successive approximation register (SAR) analogue-to-digital converter (ADC). Operating from a 2.5V supply, the device is said to feature a ±Vref fully differential input range with Vref ranging from 2.5 to 5.1V. The LTC2380- 24 consumes 28mW and is claimed to achieve ±3.5ppm INL maximum and no missing codes at 24 bits.

Industry’s most integrated Bluetooth smart module

Cypress Semiconductor has introduced a Bluetooth Smart module that it claims is the market’s first Bluetooth Low Energy (BLE) solution to integrate programmable analogue and digital blocks in a fully-certified module. The small-form-factor EZ-BLE PSoC module includes Bluetooth 4.1 qualification and worldwide regulatory certification.

Precision op amp with industry's best noise performance

Analog Devices has introduced the first in a series of high-voltage, low-noise, zero-drift, precision operational amplifiers that are said to reduce system noise, cost, board space, and development time by providing on-chip electro-magnetic interference filtering and eliminating the need for calibration circuitry.

Evaluation board strengthens support for software-defined sensor

Melexis has introduced an evaluation board (EVB) to strengthen the support available for its MLX90393 programmable magnetic sensor IC. The MLX90393 EVB offers engineers a platform for constructing a wide variety of human machine interfaces and has the potential to support more sophisticated designs such as complex 3D sensing systems, such as joysticks or rotary knobs with push functions included.

D/A converter range extended

Microchip has expanded its non volatile D/A converter product line with the addition of the MCP47FEBXX range. The low power, single- and dual channel devices feature 8, 10 and 12bit resolution, integrated EEPROM and an I2C interface.

Class D audio amp reduces component count

Integrating an advanced 32step up/down volume control, the PAM8407 Class D audio amplifier from Diodes is optimised to reduce component count in a range of stereo speaker applications, including PCs, docking stations and wireless speakers.
