Best practices guide to speaker mounting

June 10, 2025 By Aimee Kalnoskas Leave a Comment

The way a speaker is mounted can make or break its acoustic performance. Whether you’re working with miniature transducers in compact devices or full-sized drivers in specialized enclosures, proper speaker mounting is essential for ensuring optimal sound quality, minimizing distortion, and extending component lifespan. From mechanical isolation to enclosure sealing, even small mounting details can […]

How op amps work and why you should use them: part 1

May 15, 2025 By Bradley Albing

Operational amplifiers (op amps) may initially look intimidating, but with a bit of study, they can be easily understood and used in a variety of applications. Op amps can be thought of as a perfect amplifier in a black box. When we create a design using an op amp, we initially presume that the device […]

Design a circuit for ultra-low power sensor applications

April 7, 2025 By Bradley Albing

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 […]

Amplifier delivers 0.15% gain accuracy with 2.1 MHz bandwidth

March 27, 2025 By rtraiger

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, […]

What are the advantages of a three op-amp instrumentation amplifier?

February 18, 2025 By Jeff Shepard

An instrumentation amplifier (INA) built using three operational amplifiers (op amps) can provide performance advantages in terms of high input impedance, low output impedance, easily adjustable gain, excellent common-mode rejection ratio (CMRR), high accuracy, and high open-loop gain. This article examines the basic design of INAs and their performance benefits, then discusses some application considerations, […]
