Current sensors cover DC to 5 MHz

EDN Network - Fri, 02/09/2024 - 16:30

Two wideband current sensors from Allegro, the ACS37030 and ACS37032, ensure efficiency and reliability in GaN and SiC FET power architectures. With an operating bandwidth of DC to 5 MHz, the devices are suitable for electrified vehicles, clean energy solutions, and data center applications.

The ACS37030 and ACS37032 offer current sensing ranges of ±20 A, ±40 A, and ±65 A, with a typical response time of 40 ns. Both devices employ dual signal paths. One path captures low-frequency and DC current using Hall-effect elements. The other path captures high-frequency current data through an inductive coil. These two paths are summed to enable sensing from DC to 5 MHz in a single device.

The current sensors achieve stable and safe control, while reducing EMI. Sensitivity error over temperature is ±2%. The properties of the inductive coil increase signal to noise ratio (SNR) as frequency increases, minimizing noise at the output. The ACS37030 provides a zero current reference output, while the ACS37032 offers an overcurrent fault output.

Housed in compact 6-pin SOIC packages, the sensors have a rated isolation voltage of 3500 VRMS and a basic working voltage of 840 VRMS. They operate over a temperature range of -40° to +150°C. To learn more about the ACS37030 and ACS37032 current sensors, click here.

16-bit audio ADC detects breaking glass

EDN Network - Fri, 02/09/2024 - 16:29

Asahi Kasei’s AK5707 ADC packs an acoustic activity analyzer (AAA) that can be configured to detect specific types of acoustic events, such as breaking glass. This integrated analog acoustic event detector makes the AK5707 16-bit monaural ADC well-suited for IoT security applications, like wireless cameras and smart doorbells.

Consuming just 34 µA, the AK5707’s AAA block listens for acoustic events that fit user-customizable profiles. Upon detection, the AAA activates the ADC and initiates recording to an integrated audio buffer. Simultaneously, it generates an interrupt to wake the external SoC.

Unlike typical loudness-based detection, the AAA constantly tracks the current noise floor and adjusts its detection parameters in response. AAA detection not only reduces false positives, but also increases battery life in noisier environments. Asahi Kasei offers a suite of detection profiles for the AAA, including glass-break, alarm patterns, crying baby, and human voice. These profiles are configurable, with multiple acoustic parameters set by the user.

The 16-bit, 48-kHz ADC block of the AK5707, which can be powered on and off independently of the AAA, achieves a signal-to-noise ratio of 95 dB, while consuming only 200 µA. Built-in AC coupling capacitors allow for a 3.2 mm2 PCB area, including one external capacitor.

The AK5707 comes in a tiny 1.53×1.58-mm WLCSP. It is currently sampling, with mass production scheduled to begin in September 2024.
