Analog-to-digital converters are the heart of most test equipment, setting the stage for the digital processing of analog signals. Several posts over the past year or so have involved digital signal processing. For example, we have covered the fast Fourier transform (FFT), the inverse FFT, and discrete convolution. To perform these operations on real-world signals, […]

Amplifier delivers 0.15% gain accuracy with 2.1 MHz bandwidth
STMicroelectronics’ TSC1801 low-side current-measurement amplifier integrates matched resistors to set the gain, which simplifies the circuit design, saves bill-of-materials costs, and ensures gain accuracy within 0.15% over the entire temperature range. The fixed gain also eliminates production trimming of external resistors. Combining very high accuracy and wide bandwidth, the TSC1801 is used for motor control, […]
Design a circuit for ultra-low power sensor applications
Sensors monitoring mechanical and biological systems must often scavenge power from the thing being sensed. The oscillator circuits shown here let you operate those sensors. Sensor circuits that connect to thermocouples, electromagnetic mechanical-to-electrical transducers, and piezoelectric mechanical-to-electrical transducers often use oscillators powered through energy harvesting from solar cells and other sources. These power sources can […]

This module represents a dynamic IOT node, with support for Bluetooth Low Energy, Thread, and Zigbee radios and high-performance computing including an ability to run AI at the Edge. It can thus form the core of a complex IOT device with an unparalleled mixture of features, performance, and […]
Do I need an analog switch or multiplexer?
If an application calls for a device with multiple inputs and a single output, it needs a multiplexer. A switch can be used if the need is for one input per output. Analog switches and multiplexers are used in a wide array of systems, including industrial, medical, military/aerospace, consumer, 5G infrastructure, and more. This article […]
